Moving discussion to Indesign forum.
I've made a photo book in indesign but when test printed the yellows are coming out green.
The problem is consistent throughout."
IF your photos are CMYK and you are test printing to an ink jet printer--you will get what you are describing (because an ink jet printer converts the color on the fly...and CMYK to CMYK conversion produces weird color shifts).
solution: use RGB photos when printing to an ink jet --or-- ask the printing company to see color proofs before they print
Did you download the Blurb ICC profile? Have you assigned it as the working space in the InDesign file? Is your monitor really calibrated and profiled correctly (I ask this because I just had to replace my older iOne Display colorimeter and EyeOne Match software becasue they simply didn't work with my new wide-gamut monitor)?
The test print was a full pre-print copy done by Blurb on their printer (HP Indogo 5000), so it's not a home printing issue.
Good thought though.
Yes I am using the Blurb profile etc. The problem is that I made a balls up of calibrating my monitor - 100% my fault.
What I am trying to find out is whether there's a quicker way of rectifying the mistake than re-calibrating the monitor and then re-colouring each picture indivdually in photoshop?
Is it possible to export the document from indesign, then re-colour the document as a whole and save it in the pdf version 1.3 required by Blurb? If so what software would I use for this?
For reference, I am using indesign CS6 and photoshop elements 9. This is just a stop gap until my new computer arrives and I can use everything from creative cloud and acrobat pro. I point this out because there may be a solution using the full fat photoshop to colour a pdf that's been exported from indesign, but I'm unable to experiment at this time.
PS elements doesn't have a cmyk space so how are you using the Blurb profile? The placed images must be RGB. We're they correctly profiled? How did export? Was there a conversion to CMYK? Was the Blurb profile used as the export destination?
Blurb's website says the their profile is based on GRAcol, and I've used the GRAcol profile with a local printer (at their request to match the press) and their Indigo and it worked beatifully, so I think it's probably just a question of loading the Blurb profile and having the monitor correctly calibrated and profiled to do a soft-proof in ID, then export to the Blurb space if it looks OK.
Can PS elements soft proof? I've never used it. If it can't, then it's probably going to be pretty difficult to make intelligent adjustments to images on a case by case basis.
It's been awhile since I've opened it but there's no CMYK mode and I don't know how it handles RGB. You could imagine many problems with a questionable monitor profile. Plus Is the RGB coming into ID tagged with a source profile? Is the native ID CMYK color assigned Blurb or is it getting converted on export? Yellows can pick up some cyan on CMYK-CMYK conversions
