The site for prepress & print devotees

Prepressure covers design techniques, PDF, PostScript, fonts, JDF and numerous other prepress topics that have to do with printed communication and graphic arts. This site teams up with B4Print.com, the favorite stake-out of many prepress professionals who regularly visit its forums.

E-readers versus print

I only stumbled across this article recently, even though it is from May 2012: ‘Are eReaders Really Green?‘ is an interesting comparison of the carbon footprint of print and tablets. It makes the valid point that the ecological impact of manufacturing e-readers plays a major role when comparing the carbon footprint of printed books and magazines with their digital equivalents.

A look back at 2014

The ‘History Of Prepress’ section now contains a page dedicated to all the major prepress and printing news of 2014. From that page you can jump back  one year at a time, all the way to 1984. Enjoy the trip down memory lane!

RAID 6

Ages ago when my employer still sold lots of file servers, I created a page about RAID systems on this site. Because it was 1999 and the web was still young, that page became pretty popular. In fact it still ranks among the most visited pages today. I updated that page during the Christmas break, fixed some embarrassing mistakes and added a description of RAID 6. At the same time it was a nice exercise in using Adobe Illustrator to create SVG drawings. Internet Explorer 8 users won’t be able to see these, but that is something I can live with. Sticking to IE 8 is a stupid idea anyway.

Prepress Pete is tweeting

Trying to make an application idiot proof often leads to software that only idiots should buy.

The 2015 color of the year

Marsala (Pantone 18-1438) is the color of the year.

Since 2000 Pantone annually declares a particular color ‘Color of the Year’. I’ve added this little trivia fact to the pages on the history of prepress.

Specifying paper sizes

There is a new poll in the column to the right about the quality of ‘press ready’ PDF files. It replaces the previous question about how to specify page sizes, a poll that ran far too long. If you are still interested in learning how many people think a 200 x 250 mm page is 250 mm wide, visit the poll results page.

The local village idiot, also known as Prepress Pete, has been on Twitter for quite some time now. Since he cannot be relied on for any serious messaging, there is now an official prepressure.com Twitter account. If you’re serious about prepress and would like to know when new content appears on this site, please follow us. If you are somewhat less serious, consider following Pete.

New terms in the dictionary
