There are many types of bindery marks used in a pressroom, but lets limit this topic to marks for die cutting, scores, folds, and perforations. I’ve selected these four because they are required marks that many bindery and finishing services need to accomplish their tasks. What this basically means is that it is necessary to create the appropriate marks in your digital files in order to get your finishing done correctly.
Not only is this a requisite, but there is a preferred method for creating this type of graphic element. We create a large percent of these for our customers, however let us look at what it would take for you to do this yourself.
The idea here is to use your layout application drawing tools and create the shape of your dieline, score, fold, or perforation marks and/or lines. Then apply a custom spot color along with Overprint to your drawn elements. This custom color is similar to a spot color but with an appropriate custom name, like Dielines, Scores, Folds, or Perf Marks.
By selecting your marks to Overprint, the drawn art will not affect the design below it. This enables prepress operators to provide proofs demonstrating the marks, and can be removed easily when making plates for press.
If your application has a Separations preview like in Adobe® InDesign®, you can see the results on your screen. You should be able to turn off the custom bindery mark color and not see a white line beneath it.
How to Make a Bindery Mark Color
QuarkXPress®
To define your own custom bindery mark colors, simply access the Edit Color dialog box. Name: your color Dieline or anything appropriate. For the Model: pop-up menu select CMYK, and make sure the Spot Color checkbox is selected. Apply any values you want in the fields next to C:, M:, Y:, and K:. The values are not important for printing purposes, only visual ones. Press the OK button to add your Bindery Mark color to the Colors palette.
Overprint
In addition to applying a unique spot color definition for your Bindery Marks, you will also need to select them to Overprint. To apply the Overprint in QuarkXPress you need to open the Trap Information palette, then apply the Overprint option for your marks. Below are three example settings for overprinting a stroke (Line:), box (Frame Inside: and Frame Outside:), and a dashed line (Line: with Line Middle:). In each instance, by default, the popup menus are set to Default and the value fields on the right are set to Overprint (not pictured). Simply change the popup menu selection to Overprint (as shown below) and the value fields will disappear.
Line or Stroke
Adobe® InDesign®
To make custom Bindery Mark colors, access the New Color Swatch dialog box. Type any appropriate name in the Swatch Name: field. For the Color Type: pop-up menu select Spot and for the Color Mode: pop-up menu select CMYK. Enter any Cyan, Magenta, Yellow, and Black values in the appropriate fields, or use the sliders. Again, the values are for visual purposes, and are not important for print. Press the OK button when your are finished to add your unique Bindery Mark color to the Swatches palette.
Overprint
To apply Overprint to your marks in Adobe InDesign simply open the Attributes palette and select the Overprint Stoke checkbox for all your Bindery Marks.
