Post subject: | Overprint option |
I'm developing an application that needs to create prepress ready proofs. PDFSharp is working out perfectly but a request has come to me to mark the dieline (border around the shapes) as overprint so they can toggle it off in Illustrator. I'm not an Illustrator person by any means so I'm not entirely sure what's being requested. Does this option exist in PDFSharp? Thanks in advance, Mike |

You can toggle overprint preview in Adobe Reader as well (under prefs -> Page Display). I think you want to stroke the dieline with PdfExtGState.Keys.OP set to true. Frank. |

How do you set the PdfExtGState.Keys.OP to true? |

This is how I got overprinting to work... Dim overPrintBlackBrush As XSolidBrush overPrintBlackBrush = New XSolidBrush overPrintBlackBrush.Color = XColor.FromKnownColor(XKnownColor.Black) overPrintBlackBrush.Overprint = True penPoint = New XPoint(36, 36) gfx.DrawString("Overprint Black Text!", mediumRegularFont, overPrintBlackBrush, penPoint) penPoint = New XPoint(36, 66) gfx.DrawRectangle(overPrintBlackBrush, 10, 10, 20, 20) |
