Are problems likely to arise with normal printers? If so, can anyone suggest questions I should ask to help determine whether they can handle my files? Also, is there anything in particular I should do to my files to make sure they are print-ready?
Thanks in advance for any suggestions.
Matt, Being a newbie when it comes to ConTeXt, but having worked in the commercial printing busines for a decade, I would say that the majority of printers actually prefer PDF files rather than Quark, InDesign or Pagemaker files. At least that is the case in Europe, and it would suprise me if it is not the same situation in USA. The reason for this is that the printers get away from all the associated problems with the DTP program files: typfaces that are lacking, missing image links, text that may reflow etc. However, a caveat emptor: - I don't quite understand how ConTeXt:ers deal with solid PMS spot colours - i.e. not a spot colour in CMYK mode where the spot colour is made up of a screened colour mix of cyan, magenta, yellow and black, but a colour that you want to print with a specially mixed Pantone PMS ink from an additional printing plate (apart from the four C, M, Y, K process plates). However, this is frequently done in printing, so it would surprise me if ConTeXt didn't have a solution for it. - Also, I don't know whether it is possible to downsample images in PDF's that you generate from ConTeXt. If it is, avoid it. The printer expects CMYK images (not RGB!) where the resolution is approx. 2 times the screen count in the final print, @ the physical size on the paper. So if you have an image in your PDF that is 10 cms /4 in. wide, and you want it printed in a 150 lpi (lines per inch) screen, make sure the original resolution is 300 dpi @ 10 cms / 4 in. All the best, Mats Broberg
