WEEK 1 - LECTURE 1
Advanced Typography: Typographic Systems

"All design is based on a structural system" (Elam, 2007)

The purpose of learning this is to serve as a guide for placing different levels of information in the right places. It helps to provide focus in direction to understand the nuances of typographic layout and composition, something to handhold during the process of exploration. 

8 major variations with an infinite number of permutations are as follows:
1) Axial System: All elements organised to the left or right of a single axis.
2) Radial System: All elements extended or spread out from a point of focus.
3) Dilatational System: All elements expand from a central point in a circular fashion.
4) Random System: Elements appear to have no specific pattern or relationship, must be looks chaotic but there should be underlying sense of order and logic within the chaos.
5) Grid System: A system of vertical or horizontal divisions. 
6) Transitional System: An informal system of layered banding. 
7) Modular System: A series of non-objective elements that are constructed in as a standardised units. Based on units, and when using units, they should be consistent in size and interchangeable across the layout.
8) Bilateral System: All text is arranged symmetrically on a single axis.

There are some additional criteria that come into play in typographical systems, which are:
1) Hierarchy
2) Reading Order
3) Eligibility
4) Contrast

WEEK 2 - LECTURE 2
Advanced Typography: Typographic Composition

Principles of Design Composition:
1. Emphasis
2. Isolation
3. Repetition
4. Symmetry and asymmetry
5. Alignment
6. Perspective

The Rule of Thirds is used a guide, the intersecting lines are used as guide to place the points of interest.

From the 8 typographic systems, the most used system is the Grid System/ Raster System.
Other system that are used:
  • Environmental Grid: Based on the exploration of an existing structure or a combination of multiple structures by extracting the crucial lines, both curved and straight line, that are formed.

WEEK 3 - LECTURE 3
Advanced Typography: Context and Creativity

Handwriting
The shape and line of hand drawn letterforms are influenced by the tools and materials used.

Cuneiform c. (3000 B.C.E.)
  • The earliest system of actual writing.
  • Written from left to right to evolved from pictograms.
Hieroglyphics (2613 - 2160 B.C.E.
  • Was a mixture of both rebus and phonetic characters, the first link to a future alphabetic system
  • Have potential to be used in 3 different ways:
    • ideograms: represent the things they actually depict
    • determinatives: show that the the signs preceding are meant as phonograms and to indicate the general idea of the word
    • phonograms: represent sounds that "spell out" individual words
Early Greek (5th C. B.C.E.)
  • The Phoenicians developed a phonetic alphabet consisting of 22 letters.
  • Was often read in a format known as boustrophedon or "as the ox plows", one row would read left to right then switch from right to left.
  • Drawn freehand, not constructed with rule, and have no serifs.
Roman Uncials (4th century)
  • By the 4th century, Roman letters were becoming more rounded, the curved form allowed for less strokes and could be written faster.
English Half Uncials (8th C.)
  • Evolved into a more slanted and condense form.
Emperor Charlemagne
  • After the fall of the Roman Empire, the end of a central advanced culture resulted in general illiteracy and a breakdown of handwriting into diverse regional styles,
Carolingian Minuscule
  • Was used for all legal literary works to unify communication between the various regions of the expanding Europian empire.
Black Letter (12-15 C. C.E.)
  • Characterized by tight spacing and condensed lettering.
  • Evenly spaced verticals dominated the letterform.
  • Condensing line spacing and letter spacing reduced the amount of costly material in book production.
The Italian Renaissance
  • The renaissance embrace of ancient Greek and Roman culture spurred a creative wave through Italian art, architecture and letter form design.
  • Humanist named the newly rediscovered letterforms in Antica. The renaissance analysis of form that was being applied to art and architecture was directed toward letterform, resulting in more perfect . rationalised letter.
Movable Type (11 C. - 14 C.)
  • China had attempted use movable type for printing but was unsuccessful due in part the large number of characters and the materials used, which is clay.
  • In late 14 C, the Koreans establish a foundry to cast movable type in bronze, allowed the dismantling and resetting of text. 
  • To conclude, this innovation was pioneered in China but achieved in Korea (Diamond Sutra)

WEEK 4 - LECTURE 4
Advanced Typography: Designing Type

1) Adrian Frutiger - Univers 
Adrian Frutiger was a Swiss graphic designer of the twentieth century, known for his valued contribution to typography, including Univers and Frutiger typefaces. Frutiger is a sans serif typeface. The goal of this new typeface was create a clean, distinctive and legible typeface that is easy to see from both close up and far away. Extremely functional.

2) Matthew Carter - Georgia & Verdana
Many of Carter's fonts were created to address specific technical challenges, for example those posed by early computers. The purpose of the font was to maintain high legibility, even at very small sizes on the screen due in part to the popularity of the internet and electronic devices. Off screen, Georgia & Verdana have also been used in print. In 2010, there was a lot of "frontoversy" when it was announced that IKEA would be changing from Futura to Verdana.

3) Edward Johnston - Johnston Sans
Edward Johnston, the creator of the hugely influential London "Underground" typeface, which would later come to be knows as "Johnston Sans" (1916). He was asked to create a typeface with "bold simplicity", one that felt modern while still reflecting traditional values. The purpose was for London's Underground railway that ordered a new typeface for its posters and signage from the calligrapher Edward Johnston. He handed over details and examples of letterforms that would set the tone for printed text until the present day.

4) Eric Gill - Gill Sans
His former student was perhaps driven by the guilt over the success of his own typeface, Gill Sans, which he admitted had been heavily inspired by Johnston's design.

Type Design Process:

1. Research 
- When creating type, it is essential to understand type history, type anatomy and type conventions. We should also have knowledge about terminologies, side bearing, metrics, hinting.
- Then, it is important to determine the purpose of the typeface, considering what it would be used for, what different applications it will be used in such as whether the typeface is for school busses or airport signages, etc. 
- We should also analyze existing fonts that are presently being used for inspiration/ideas/reference/context/usage pattern/etc.

2. Sketching
Some designers prefer sketch their typeface using traditional tools like brushes, pens, ink and paper.

3. Digitization 
Professional software that are used in the digitization of typefaces are: FontLab and Glyphs App. Some designers also use Adobe Illustrator to design or craft their letterforms first, then introduce it into the specialized font apps.

4. Testing
The results of the testing is part of the process of refining and correcting aspects of the typeface. Prototyping is also part of the testing process and leads to important feedback. Depending on the typeface category (display type/text type) the readability and legibility of the the typeface becomes an important consideration. However it is not as crucial if the typeface is a display type, where expression of the form takes a little more precedence. 

5. Deploy 
Even after deploying a completed typeface there are always teething problems that did not come to the fore during the prototyping and testing phases. Thus, the task of revision doesn't end upon deployment. The rigour of the testing is important so that the teething issue remains minor.

Typeface Construction


Figure 1.7: Construction grid for the Roman Capital (8x8 cells),
source: Lecture Video Advanced Typography - Designing Type, Week 4 (13/05/2025)

Roman Capital letter can be constructed using the grid system. The grid consists of a square with a circle inside that touches the square's sidesat four places. Within the square, there is also a rectangle. This rectangle is three quarters the size of the square and is positioned in the centre of the square. 

Using grids (with circular forms) can facilitate the construction of a letterforms and is a possible method to build/create/design your letterform.

Construction and considerations

Figure 1.8: Construction and considerations,
source: Lecture Video Advanced Typography - Designing Type, Week 4 (13/05/2025)

Many different forms and constructions must be taken into account when designing a new type. An important visual correction is the extrusion of curved (and protruding) forms past the baseline and cap line. This also applies to vertical alignment between curved and straight forms. 

A visual correction is also needed for the distance between letters. It is not possible to simply place letters next to each other with equal spacing between them. The letters must be altered to a uniform see. 'visual' white space. This means that the white space between the letters should appear the same. This is called ‘fitting' the type. 

For a design to be successful, the designer must be deeply invested in the idea, fully understanding the requirement, limitations, use, and the needs of the stakeholder. Designing a typeface is a labour of love.


INSTRUCTIONS



Task 1: Exercise 1 - Typographic Systems

In the first exercise, we were given the chance to explore 8 typographic systems using Adobe InDesign only. Adobe Illustrator was permitted but only for very specific, limited use. The artboard size should be 200 x 200 mm. In addition to black, we were allowed to use one other color. Graphical elements could be used, but only to a limited extent.

From the three text options given, I chose the following text:

Task 1: Exercise 2 - Type and Play

Part 1
Students will analyse, dissect and identify potential letterforms within the dissected image. The forms would be explored and ultimately digitized. It is expected that through a process of iteration the forms would go from crude representation to a more refined celebration that would reflect to a degree its origins.

Extracted letterforms go from crude representation to a more refined expression but yet maintaining core features of its origin. It is good to have a sample font for direction and reference when refining

Part 2
Upon completing the letterforms, students will combine the letterforms with an image that is the basis of the extracted letters. The objective is to enhance/support the interplay between the letterforms and the selected visual. The text must be woven into a symbiotic relationship with the image.


Task 1: Exercise 1 - Typographic Systems

Visual Research

First of all, I did visual research, mostly using Pinterest. However, some of my inspirations didn't come from existing layouts, but from real-life objects. For example, my inspiration for the axial system came from a zipper. For the transitional system, I was inspired by a rope, imagining it rotating to guide the flow.

Reference Sources

Axial System

Radial System

Dilatational System

Random System

Grid System

Modular System

Bilateral System

Transitional System


Sketch

I then start sketching my ideas using ProCreate. 

Figure 2.2: Sketches, Week 1 (26/04/2025)
InDesign Process

I used both serif and sans serif typefaces in this task ro create more variation. For the body text, I used sizes ranging from 8 pt to 12 pt, with leading set 2.5 to 3 pt higher, as taught by Mr. Vinod in the first semester in typography class. I adjusted the gutter based on the typographic system used. I applied 10 mm margins on the top, bottom, left, and right for all systems. I added red as an additional color to match the title, except for one attempt of the transitional system, where I used blue instead.

First Attempt - Week 1
Then, I began working in Adobe InDesign, but there were some changes from my original sketches during the design process in InDesign.

Figure 2.12: Transitional System - Attempt #1, Week 1 (27/04/2025)

Second Attempt - Week 2 (Revised and Further Exploration)
Mr Vinod accepted most of my work, 

Figure 3.1: Compilation of My First Attempt, Week 2 (28/04/2025)

  • Axial System: Mr. Vinod preferred option #2.
  • Radial System: Both options were considered acceptable.
  • Dilatational System: He liked option #2 but pointed out that the two bold texts at the bottom need to have consistent sizing in spacing like the other.
  • Random System: Option #1 is acceptable.
  • Grid System: He approved options #2 and #3.
  • Modular System: Option #2 was considered decent.
  • Bilateral System: Option #1 does not qualify as a bilateral layout, but option #2 is correct.
  • Transitional System: Option #1 is okay.
Based on Mr Vinod's feedback, I decided to make improvements to the random system, as it seemed he wasn't fully satisfied with my first attempt of random system. To be honest, the random system has been the most challenging one for me. As someone who tends to work in an organized way, embracing randomness doesn't come naturally. Then, in the class Mr. Vinod said that the random system is the most visually exciting, but it's also one of the hardest to execute, especially if you're naturally an organized person. Your structured mindset might resist the disorder, so it requires a flip. You have to fully embrace and throw caution to the wind. Let chaos reign supreme in your work, but should be underlying sense of order and logic within the chaos.

Task 1: Exercise 2 - Type and Play Part 1

Finding an Image
First of all, I needed to choose a subject to extract. Then the idea of 'Jepara wood carving' came to my mind, as carvings are naturally form letter-like shapes. The idea came to me because Jepara is a city in Indonesia, which located on the northern coast of Central Java. It is famous for its wood carving industry. 

Figure 5.1: Chosen Subject, source: Ukiran - Jepara, Week 2 (03/05/2025)

Extraction
Then, I began extracting the letterforms and modifying them using pen Tool in Adobe Illustrator.

Figure 5.2: Letterform Extraction, Week 2 (03/05/2025)

I chose ITC New Baskerville Std Roman as the reference font.

Refinement Process - First Attempt

Figure 5.5: Refinement Process with Baseline, Week 2 (04/05/2025)

Figure 5.6: Process Compiled, Week 2 (04/05/2025)

From the feedback, Mr. Vinod noted that there’s some things to sort out in the design. For the letter ‘c’, he pointed out that a small point on the lower left side is too sharp. He mentioned that the letter ‘d’ is good overall but suggested reusing some parts to maintain consistency, and when doing a mirror, make sure to pay attention to the consistency of the thickness. When I asked if it was okay to create a letter from separate alphabets I noticed in the design, he confirmed that yes, you may do such things.

Refinement Process - Second Attempt (Revised and Further Exploration)

Since Mr Vinod say that it was okay to create a letter from separate alphabets I noticed in the image, so I decided to remove the extracted letter 'd' and extract letter 'l' because letter 'd' should actually be constructed from the combination of the letter 'l' and a flipped 'c'. Here is what I did" 
  • Made the letter 't' using the letter 'l' and created the top line by rotating two 'c' letters. 
  • Formed the letter 's' from two letter 'c'
  • Created the letter 'p' by rotating the letter 'l' and adding a letter 'c' to form the bowl

Task 1: Exercise 2 - Type and Play Part 2

After finishing the letterforms, I started working on the poster. For the background, I searched for a sculpted painting on Google. 

Figure 6.1: Original Photo (source: https://pin.it/11i1W5Wfr), Week 3 (06/05/2025)

First Attempt 
Then, I proceeded to Photoshop, where I cropped the original photo to 1024px by 1024px and applied filters. I used black & white filter, adjusted the hue/saturation, and also modified the brightness & contrast to achieve the desired background color.

Figure 6.2: Process in Photoshop, Week 3 (06/05/2025)

Then, I moved to Adobe Illustrator. To begin, I inserted the background I had edited earlier, then I added the letterforms I had created. Next, I applied gradient color to the text to enhance its visual appeal and match the 'sculpt' title, also I applied a white color outline. I then added the 'DTS', 'Dolby', and 'Parents Strongly Cautioned' logo, as what Mr. Vinod instructed in class.

Figure 6.4: Task 1 - Exercise 1: Type and Play - JPEG, Week 3 (07/05/2025)

Second Attempt (Revised and Further Exploration)
Mr. Vinod said that it was a good attempt, but the text is not really legible. You can make the title more prominent. So I decided to adjust the brightness and contrast of the background in Photoshop.

FEEDBACK

WEEK 1 
General Feedback: Mr. Vinod briefed us about the Module Information Booklet and the rules, and he explained our first task. He instructed us to carefully read the post on Teams, watch the pre-recorded lecture and tutorial videos provided, and complete some exercises before the upcoming week. 

WEEK 2 (EXERCISE 1: TYPOGRAPHIC SYSTEMS)
General Feedback: Mr. Vinod emphasized the importance of setting margins and gutters before starting the task, margins part must be empty. He highlighted that the modular typographic system is based on units, and when using units, they should be consistent in size and interchangeable across the layout. He also mentioned that too many decorative elements is distracting. Regarding the axial typographic system, he advised not to use angles that are too aggressive.
Specific Feedback:
- Axial System: Mr. Vinod preferred option #2.
- Radial System: Both options were considered acceptable.
- Dilatational System: He liked option #2 but pointed out that the two bold texts at the bottom need to have consistent sizing in spacing like the other.
- Random System: Option #1 is acceptable.
- Grid System: He approved options #2 and #3.
- Modular System: Option #2 was considered decent.
- Bilateral System: Option #1 does not qualify as a bilateral layout, but option #2 is correct.
- Transitional System: Option #1 is okay.

WEEK 3 (EXERCISE 1: TYPE & PLAY PART 1)
General Feedback: Mr. Vinod mentioned multiple times the importance of maintaining consistency in the construction of each letter, especially in terms of thickness.
Specific Feedback: Mr. Vinod said that my work is interesting and that he liked how I chose something very creative. However, he noted that there’s some things to sort out in the design. For the letter ‘c’, he pointed out that a small point on the lower left side is too sharp. He mentioned that the letter ‘d’ is good overall but suggested reusing some parts to maintain consistency, and when doing a mirror, make sure to pay attention to the consistency of the thickness. When I asked if it was okay to create a letter from separate alphabets I noticed in the design, he confirmed that yes, you may do such things.

WEEK 4 (EXERCISE 1: TYPE & PLAY PART 2)
General Feedback: Mr. Vinod mentioned the importance of margins again. He also emphasized that the key is to always try your best and not let harsh feedback get you down. The purpose of the feedback is not to break you, but to help you learn from it. It's important to apply those skills and that knowledge in the workplace. Focus less on grades and more on the work you are doing.
Specific Feedback: It was a good attempt, but the text is not really legible. You can make the title more prominent.


REFLECTION

Experience
For exercise 1, to be honest, I felt quite overwhelmed as I needed to finish 8 typographic systems in a week. I was worried that my work wouldn't be accepted by Mr. Vinod, so I decided to create multiple options for each layouts as a plan B. However, in class, I learned the most important lesson, which is to be confident in my own work and to trust my own judgement, even towards our own work. What really hit me was when Mr. Vinod said, "What's the point of getting an A if you learn nothing? Do not be afraid to make mistakes, learn to trust your own judgement towards your work as you need those things later on at work. Do not always rely on my judgement because you won't upgrade and learn." Since that moment, I've felt a greater sense of freedom in doing my task. I've stepped out of my comfort zone and become more confident in coming up with different ideas, just like the carved painting I chose for extracting letterforms in the 'Type and Play' exercise. Usually I tend to come up with ideas similar to the samples Mr. Vinod provided. Mr. Vinod gave us a leaf picture to extract as an example, and typically I would look for similar ideas. But this time, I chose something different, and turns out that Mr. Vinod liked how I chose something very creative and interesting. However, there was still a lot to revise in that work, but because Mr. Vinod statement earlier, I am now learning from every mistakes I make. I agreed that GPA is important, but now my perspective has shifted. I value the lessons I learn from my mistakes more, lessons that will stay with me and help me avoid repeating them. Thanks to Mr. Vinod, for pushing us in that way.

Observations
From 'Typographic Systems' exercise, I observed that balance plays a crucial role in arranging layouts. This task helped me to notice the importance of leading, alignments, etc. It also makes me to recall the lesson I learned in the first semester. While from 'Type and Play'  exercise, I realized that incorporating meaning into a design significantly enhances its value.

Findings
I found that this exercise really pushed myself to explore more than I used to be and come up with different ideas. I started stepping out my comfort zone since the 'Type and Play' exercise, the moment after Mr. Vinod shared the lessons I mentioned earlier. I realized that exploring can actually be really fun and turns out I found myself can come up with unusual ideas. I found that these exercises helped me and pushed me to dig deeper into my potential.

In the process of making the random system, I had difficulties because I have no idea how to think random, so I read this book in order to have deeper understanding about this system. 

Figure 7.2: Random System (Page 72), Week 2 (04/05/2025)

Random System (Page 70 - 85)
  • Nonobjective Elements
    • These elements need to appear as free and unconstrained as the text in their form and placement.
    • They can modify a word or line and improve communication in visually chaotic environment.
  • Shaped Background
    • Incorporating a shaped background with unexpected angles adds complexity to the composition.
  • Repetition
    • Repetition can create engaging compositions, while excessive repetition of type elements in pursuit of an interesting textural composition rapidly leads to loss of communication.
Random system is composed of elements that are arranged without a clear aim, pattern, direction, rule method or purpose.
