    Preflight warnings for registration color -- how to avoid?

    Arbor Vitie Community Member

      In preflighting, is there any way to turn off registration color and font color warnings when checking for spot colors and non-CMYK colors?

       

      I spend a lot of time tunneling through lists of fonts (that use non-CMYK color in their definitions) and registration color notes for crops, register marks, and so on, just to make absolute certain that the "Object uses non-CMYK color" info doesn't contain anything weird.

       

      I've recently moved from CS3 to CS5 Acrobat Pro 9, and hoped there would be some option to turn off font color and registration color messages.

       

      Thanks.

          Which exact Preflight Profile are you using?

            It's a custom profile to check for:

             

            color and gray scale images lower than 266ppi

            more than 0 spot colors

            RGB objects

            non-CMYK objects

            Font not embedded

            transparency used

            line thickness less than .2 points

            white fill or stroke overprint

            document generate more than four plates

             

            We get files from all over created by all different levels of artists.

              Could it be »Registration color inside TrimBox« is part of the Custom checks of that particular profile?

              And the pdfs are improperly boxed? (Which one could remedy manually.)

                Good idea, but that registration check isn't part of the preflight profile.

                 

                We don't need the register marks at all since the PDF become part of a larger document. Our output bureau requires we not add slugs.

                 

                We don't have the time to correct registrations or send them back to the client ... tight deadlines, small staff.

                 

                It's not a real problem, just an annoyance mainly for that insecure feeling I get if I don't check every single alert in detail that I might miss something.

                  Sorry, I misinterpreted the original post then in all probability.

                   

                  What is the exact wording for those flags?

                   

                  If there are elements with non-CMYK-colors those will naturally also be present in Registration color; how do you handle those non-CMYK-elements anyway?

                    Non-CMYK elements are flattened (if necessary) and converted to CMYK using the fixups, but then they have to be proofed carefully for problems, so it isn't anything we want to add to the routine unless absolutely necessary.

                     

                    ===

                     

                    Example alerts:

                     

                    "Object uses non-CMYK color (52 matches on 1 page)"

                     

                    In the detail folder (after clicking on the open triangle) there are a dozen or so of these, or close variations:

                     

                    "Page 1: stroked: 0.25 pt 'Registration color'  Black (0.0) overprint: off"

                     

                    Plus nested folders labeled:

                     

                    "... Page 1: Further matches (20 out of 42)

                     

                    ... with nested folders with more alerts in that.

                     

                    ===

                     

                    If it were a simple list, I could scan it for problem, but with all the nested folders and scrolling, it take a fair amount of time (multiplied by 30 or 40 documents, say).

                     

                    Thank you for your attention. I really appreciate it, though I think my problem is small. I was just hoping there was a way to "ignore registration color in preflight" somewhere that I hadn't found yet.

                      I may be wrong, but couldn’t you customize a copy of the non-CMYK-check by adding a provision to flag only if it is not 500% for fill and stroke, one that it is not 600%, etc. depending on the number of channels likely to be about may work? (see screenshot)

                      Edit: That may need some testing at least.

                        You're my hero. I use Acrobat rarely, so I'd never found the panel in your screenshot, though I knew it must be there.

                         

                         

                        I made a custom "CMYK-no registration" check with these parameters

                         

                        Object uses CMYK (is not true)

                        Object is registration color (is not true)

                         

                         

                        It seems to work, but I'll test it thoroughly before I rely on it. The only non-CMYK, non-registration color it found in my initial test was in a couple of fonts, which is no problem to ignore.

                         

                        That just goes to show you: when you don't know what you don't know, it's hard to explain it to someone who does know.

                         

                        Thank you so much. I've marked your answer as correct, with the caveat that I didn't actually use the 500%, a very clever solution, but one that wasn't needed because of the "registration color" parameter.

                         

                        Thanks again.

                          Ah, so I overcomplicated the matter …

                          Anyway, please do give it a thorough test to assure it does not suppress cases you do want flagged.
