Thinking this is NOT an issue of typical missing Color Management know-how, but maybe really a failure in CorelDraw RGB pdf export(!?), because whatever I am trying to set (CM off, CM sRGB, etc. etc. etc. ...), and also pdf export settings:
When I export vector graphics to RGB/sRGB and open the pdf in another software (like Serif Page Plus, Adobe etc.), the color values are variying a little bit.
For example, my gray value of a logotype in Corel was 118, 115, 113.
Now I export as pdf (many logical!! setting of CM tried!!!), any other software that opens the document - also CORRECT CM settings - values are 117, 115, 112. --- The same light variations nearly anytime with any RGB color. Not possible to create vector pdfs of logos for my clients correctly this way! Really bad.
Instead of starting a discussion about Color Management Settings, could any professional, maybe a Corel member check this behaviour in practice and give me a feed-back!? - In the best case let me know the complete settings for Corel CM and pdf Export to get the RGB pdf export done correctly.
Thank you so much!

(I am currently using X4, but know that same behaviour from X3 and passed again hours to try really all reasonable CM and export combinations, at least I think so. Windows7 and WindowsXP)
What are you viewing the PDF in? Pittston Pro allows you to choose between percentage and 0/255
I do not watch PDF in Acrobat, just looking "code" PDF in Notepad.
Three squares drawn Corel: one after the other filled with color:first: R12 G12 B12second: R13 G13 B13Three: R14 G14 B14Everyone has a different outline color (in order: magenta, cyan, yellow).
Following the publication of PDF as "native" in the code you can see their definition:
As you can see, underlined in red lines are the definitions of fill. Each consists of three components and all are identical. And they all have two decimal places.The value of each component is 5% shown as 0.05.
Above each highlighted line is the definition of the color contour of each of the squares in CMYK (4 components).
So export filter with Corel to pdf, save the color to two decimal places. Conversion of a range of values from 0 to 255 scale from 0 to 100 and rounding the filling:for the first: 12/255 = 0.047 = 0.05for the second: 13/255 = 0.050 = 0.05for the third: 14/255 = 0.055 = 0.05cause color uniformity fillings.
For comparison: pdf Adobe Illustrator (already without contours)
Yes. Two experiments: RGB pdf and pdf without conversion.

There is a dll in your ZIP file.
Open this PDF in the application of your choosing--CD, PP, AI. It uses the values in your opening post.

EDIT: I just noticed this is in the X4 section. Sorry. this is from X7 and I have no other versions installed anymore.
