joliett -> COVER COLOR PRINTED TOO LIGHT??? (10/8/2007 1:24:34 AM)
I had printed a cover that was supposed to be black with white letters. The first printing was fine. The second printing by the same publisher with the same artwork turned out a few shades lighter. So much lighter that I am refusing the order. The printer claimed that the hues could change and that the only way to asure a rich black would be 3 color process - while I used 1 color - black. Is that all true? Here is a pic of the center book showing it's LIGHTER color black [image]http://hotimg5.fotki.com/b/76_15/58_28/DSCN2628.jpg [/image]

This is true whenever you have large areas of black you should use a Rich Black. Many company have different builds we typically use a build of C= 40% M =40% Y= 60% B= 100% this will give you consistently a deep true black but make sure you properly trap and text

They are blowing sunshine up your skirt. They are suppose to be the professionals here. If they thought they needed support colours, they should have added them before they made the plates. We do this all the time based on coverage, reverse type size or if there is screens involved. If this is a photo of your book, it does not look like it needed the support colours. No neeed to guess here who is wrong here. Pantone publishes a digital colour standard for every colour including black. This has listed an industry standard density reading as well as a Delta E *LAB reading for every colour. Ask the printer to read the density of the black for you. If they do not have a densitometer or a spectrophotometer, take your book to a larger printer in your area and ask them if they can read the density for you. Black density (by Pantone standards) should read 1.75. Gracol or any other widely accepted industry standard have black reading as low as 1.65 for process work. On line work (black and white printing), we would run the black at 1.85. The industry standards have a + or – of .05 tolerance. If your black falls below this standard (since there was no support colours), you have a case. In other words, if the black density falls below 1.60 it is their fault. If it does not, you are out of luck. A good printer would have compared this print to a previous print and a red flag should have gone up. Good Luck

At my shop we run "rich black" or four color black with cmy 50-40-40. The cyan overhang keeps it neutral. Usually if you are just wanting it to stay black you can just put a "punch" under it, cyan or magenta either one. People bring in one color jobs that they wants to be pitch black and only want to pay for one color but we throw the punch under it anyway so it looks good.
