Hi all, I am working on a document in Scribus 1.3.4, and am having trouble getting one color to come out right.
I have a background image that is almost entirely black and white (with just a little grey due to antialiasing)--it's an abstract pattern based on a photo of tree branches. Anyway, I have overlaid the image with two colored rectangles--one is blue, the other is yellow (specifically, it is Gold1 from the standard Scribus palette--CMYK=0, 0.16, 1, 0). Both rectangles have their fill opacity set to 100%, but I am using different blend modes--Darken for the blue rectangle, and Lighten for the yellow one. The result I am trying to achieve is black "branches" on a blue background, and yellow branches on white in the other. Everything looks as it should in the normal Scribus view and in the print preview, but when I export to PDF (PDF 1.5, Output intended for printer), the yellow changes to something more like beige (it looks this way when I display the page in Acrobat Reader, and when I print). The changed color is bad enough by itself, but I also have some text in the same shade of yellow, which prints out correctly--i.e. the text and the graphic are supposed to be the same color, but they are different. Now, I'm thinking the problem may be due to the background image being in RGB colorspace--indeed, I converted the image to CMYK, and I then get the desired colors when I view the PDF in Acroread--so I am guessing the printed result will also be good. However, that converted image isn't usable for the final product. I used the ImageMagick 'convert' program, and the results are rather bizarre: the image is indeed CMYK, but it also gets stretched and cropped in an arbitrary fashion, and black and white are inverted. So I'm not sure how to get a usable CMYK bitmap image. For image editing I mainly use GIMP 2.2, which doesn't really handle CMYK.
