    Rule below overprints descender

    RobertKyle Community Member

      We've been using the rule-below in some paragraph styles that use green type. The rule is tight to the baseline, so the descenders extend past it. On our old template, the green covers the black rule. But we've recently made a copy of that template and now the black rule is visible across the green descender.

       

      It does not display this way. On screen it appears that the green is covering the rule. But on output, the black is visible across the green. We're using the same printers and presets as before. The new template is a copy of the old, but many modifications have been made.

       

      The rule below is applied by a paragraph style. The new style is a copy of the old but at a slightly smaller type size. The rule-below size has not been changed.

      The green type is applied by a character style using a swatch.

       

      I am completely baffled.

          I can't answer for the prior behavior, but chances are, your preferences are set to "Overprint the [Black] Swatch at 100%" (See Preferences > Appearance of Black)

           

          Experiment with setting the rule color at something less than 100%K.

            It sounds like the green text is set to overprint (the black overprint won't matter because it is behind the type). You have to turn on Overprint Preview to see the print effects of overprinting. So here you can see my window shows I have [Overprint Preview] on, with the top green line set to OP and the bottom line set to knockout:

              Thanks, both for helping me find the right direction.

               

              In this case, the scene of the crime turned out to be the character style that invokes the green swatch. In the Character Color settings, there's a checkbox for Overprint Fill. It was in a mixed state: checked but grayed out. Two clicks turned it on and off, and that did the trick.

               

              It was in the same off state in our old template too. Odd that it would work one way there and another way on the new page. But the old template will be dead in a few days, so I ain't all that curious.

                Is the green mix identical? If there's any percentage of black in the mix overprint will have no effect:

                  Swatches are identical and the K value is 0.

                   

                  Here's the setting that seemed to be causing trouble:

                  In the new template, Overprint Fill is off and that seems to work.

                    With Overprint on you would expect the problem.

                     

                    Some printers turn off overprints in their preflight, or if there's a color conversion at output you would likely get some black in the conversion and the overprint would no longer happen
