I have been collaborating on a project where the graphic designer is using InDesign (CYMK environment). Some of my diagrams were placed in InDesign. Despite using the same PMS number our colours did not match. The result was a fair bit of 'tooing an frowing' with the Printer. All this costs.
I'm looking to avoid this problem in future. I'd like to clarify:
1 Are Vectorworks PDFs in RGB? (there doesn't seem to be any way to choose either CYMK or RGB when exporting to PDF)
2. Which Pantone lists does Vectorworks use? The Printer tells me that Pantone changed their lists a few years ago. For example, we wanted to use Pantone 5757C.
Pantone 5757C in InDesign CS5 is C=27%, Y= 0%, M=95%, K=55%
In Vectorworks equivalent values for Pantone 5757C are given as 0.024,0.00,0.278,0.561. The Printer tells me these convert to percentages viz: C=2.4%, Y=0%, M=27.8%, K=56.1%. Definitely not the same colour even allowing for different paper!
I use a PC.
Am I doing something wrong? Is there a way to work around this please? If the PDFs from Vectorworks are RGB wouldn't this have implications for printing generally and being able to show the client reasonably accurate colours?
