@pjbialas i hope they didn't use the term 'dpi'! yes, i can help you. please email me directly rick(at)hidefcolor(dot)com with complete specs for your book. are you looking for hardcover smyth-sewn book?

@hidefcolor ... My (US)printer does not have a CMYK profile, they said to check the dpi after conversion then if over 300 send them a few pics and they will review them. Any reasonably priced printers you can recommend? photography book 150 pages hardcover 500-1000 copies? My mom has connections in China so I am getting a quote from a reliable source there as well, but as you can imagine there is a bit of guesswork with translation and the middleman is not a printer...

@pjbialas 'convert to profile' is near the bottom of the 'edit' menu in Photoshop. consult with your printer on what CMYK color profile they print to. if they do not have their own CMYK profile, you might want to reconsider them. most printers will print to the SWOP CMYK color profile. however, SWOP is a small gamut compared to other profiles. it can be quite tricky dealing with profiles, but it is a science and good science is repeatable and expectations are met. does this help you?

@hidefcolor - Where can I find "convert to profile"? I followed this video and my pics looks a bit blurry and dull, so I'm planning to print on my home computer which uses 4 inks to see if it looks dull if so.. I need to convert 200 images to CMYK and attempt to keep the quality. The printer who will be making the book is sheet fed. Any advice? should I just leave it in RGB to the printer rather than send crap CMYK and hope their printer fixes it? I will be getting a sample before final

[hidefcolor]

yes. keep in mind that the conversion to CMYK will occur when you export your indesign document to PDF. this will preserve your indesign document, with RGB images, for other forms of media such as digital magazines and other interactive apps. the CMYK images will be inside your PDF that is ready for prepress. does this answer your concern?

My photos are in RGB, should I finish everything in indesign (100 pages) then go back and do this at the end? thank you.. Converting to cmyk in photoshot loses a bit of color so I look forward to trying this

@bbodish Depending on your print job specs, your printer will either use SWOP or GRACoL print specifications. If you're printing on a sheetfed press, hopefully your printer will print to the GRACoL specification as SWOP is geared toward heatset web printing.

Let me know if you need further information....

@bbodish Never use 'Mode' change to convert your images to CMYK. You will obtain the best color re-mapping by using 'Convert to Profile'. There is no generic CMYK color space and CMYK is a device dependent color space - meaning each paper/ink/device will have its own unique CMYK color gamut. Your printer is converting to CMYK based on their profiles that they have built using a specific paper/ink/press configuration. It is best practice to work in RGB and convert to the proper CMYK profile last.
