:) you mean many not any :) I'd stick with TIF or JPG if you want Quark to convert RGB to CMYK, 300ppi is a good ballpark for Litho pictures and you can get away with a lot less if the subject is forgiving. Not sure where quark is with a re-occurring bug that converts hi res bitmaps to 300ppi images in pdfs when any downsampling is asked for any image type?, and also Quark's downsampling is poor compared to results using Acrobat's Optimiser or Photoshop so best to leave this bit on Do not downsample.Jean-Marie Schwartz wrote:If your output settings are correct, any RGB image shall output in CMYK. HTH.
I'm not sure I want to open this can of worms, but the default AsIs (which happens to be my recommended default Litho settings) will remove any ICC profiles on the placed RGB, meaning that the RIP or Acrobat will have to be told what they are/were, which is kind of a problem if any of them were different to each other (or in the admittedly unlikely scenario of profiled RGB being supplied by someone who understands Color Management). What you end up with in a PDF would be DeviceRGB which your Litho Printer will be working blind to convert, Incorrect selection of sRGB and Adobe RGB are going to give different CMYK results. Will quark10 will finally be able pass ICC profiles through to PDF ?!? Graham are you allowed to confirm or deny ?!?Graham PM (Quark) wrote:The other option, which is somewhat easier, is to change the output set up to AsIs: your RGB images will be written out as RGB and then it is up to your PostScript RIP or PDF reader (Acrobat) to do the necessary CMYK conversions for print, at which point the end device characteristics are known.
