PDFs Generated from Quark Too Light

[C._Hanna@adobeforums.com]

Since I upgraded to OS X last year, I've been having real color problems with my PDFs. I'm using Quark 4>Distiller 5>Acrobat 5. When I open the PDFs generated from Quark files in Acrobat under OS X, they are uniformly too light.

I don't have money to upgrade everything at once, so I've been proceeding on a immediate needs basis. If I upgrade Acrobat so that I using a native version of Distiller, will that help? Or do I need to focus on upgrading to Tiger and then to Quark 7.

Any help appreciated. I had things under control in OS 9. As far as X goes, still a little wobbly on my pins.

I am having a similar problem. Some graphics get lighter when exported as pdf from Quark 6.5. In some cases the graphics were originally received from a third party as a pdf, converted to jpg or tiff in photoshpop CS2 and used in the Quark document. Third party graphic was a digital image input using Picture It!, inserted into Hallmark ??? Publishing program to create an ad. A pdf file was created using Acrobat Distiller 7 and emailed.
After converting her pdf file to jpg in Photoshop, I put in a Quark Document which printed fine. This ad was placed in a page layout with other ads and a pdf created to send to our printer(newspaper). In this pdf file the graphic was lighter but we thought it would print darker on the press. The printer opens the files in InDesign CS2 on a PC and outputs to a MAKO rip. This copy was lighter than yet and was hardley descernible on the press run. The type in the original pdf file does not get lighter, only the graphic.
Some other graphics have the same problem but not all. I have not tracked down how they were created.
Any thoughts on this subject.
Hope I do not distract from the C Hanna's request but thought the problems were relatyed!
