Lecture review: Adrian Sleeman

This lecture focused on the present situation and trends in print technology in 2011.



Prepress, is between the creation of print layout and printing, included the following items:

1 Typesetting
2 Copy-editing
3 Markup
4 Proofing
5 Proofreading
6 Screening
7 Imposition
8 Separation
9 Manufacturing of plates
10 Manufacturing of a high-quality print (PDF) file
11 Paper select: choosing a proper paper is also a very important step in prepress.

In the past decade, the prepress was divided to each technician, however, now graphic designer are taking charge of 1 – 3 processes in their responsibility. Even digital print process doesn't need to make plates for printing.

Printing machines are dramatically developing. There is almost no material cannot be printed on. Even machines can print on stones and foods etc. 7 colours inks (CMYK + 3 mores) are adopted in Germany, and increasing of environmental awareness, soy-based ink is widely used instead of oil-based.
However, Adrian quite suspected using recycling paper. Actually, managed forrest for paper less damage environment than the process of paper recycling in terms of energy consumptions and carbon dioxide emissions. He was skeptical that Primark adopted recycle paper for their shopping bags. If they radically concern environmental issues, they may have to reconsider their amount of production and its lasting.

Colour profiling is another big issues in printing industries. Now the printing process depend on digital technologies, but each computer has different colour balance on its monitor. We definitely need some measurement to define exact colour person needs. The best way is using provided colour profile from the printer. However, colour balance can be changed by the colour of paper as well. Some paper colours blue-white, others are yellow-white. These problems are concerned on the digital colour proofing stages. Printers often have to simulate the exact finishing colour on the proof sheet. In this case, they firstly scan a sheet of paper which client chose, then place it on a proof sheet. Then, they finally place images and texts on it.

So, digitalising brings faster process, more potential of colour or printing methodologies,
however, designers now more need knowledges of printing and colour proofing.


Here are some extra pictures when I visited the printing company Shashinkagaku Co, Ltd. in Shiga, Japan in July 2006.
