(I found a similar question in this forum through google but it wont let me view it, probably cause its old since 2015)
Im working on AI and I'm using a custom made brush that looks like a pencil.
Switching between GPU and CPU preview, the looks change. The GPU is more pixelated, and I like the end result more this way, however when I export its coming out like the CPU view version.
Is there a way I can export it and make it match the GPU looks & charateristics? I know I can take a screen shot, but that will loose the vector, size, etc
(edit) Comparison image attached
thanks in advance
What format are you exporting to? Which method and settings?
Would it be possible to show us screenshots of the CPU/GPU versions, and the exported file?
I'm exporting to PDF high quality preset.
I can try to save a comparison and upload here if it helps
adding screen shots as request
left side GPU, right CPU
as you can see the left side is more pixelated, and in this particular case i'm looking to emulate pencil brush strokes, which for my personal preferences gives a better result.
There's no rasterising when you save as PDF, so effectively you're asking the PDF viewing application to emulate a peculiarity of Illustrator's rather flawed GPU preview.
You're probably better off not using GPU preview, and doing what you can to get your work looking how you want it to look using the more stable and accurate CPU preview.
The GPU preview difference is a bug. It sometimes does not represent the true image. I'd suggest altering your custom brush to match the "GPU" appearance in "CPU" preview.
I have this same problem, and thought I could alter the brush to have hte same look as the GPU, but there's really no way. I wish there was an EXPORT GPU preview option, similar to options for HINTED and SUPER SAMPLE options. That would actually be a great place to put such an option.
As every helper answering so far has said/implied, viewing artwork in GPU is sometimes misleading, and the artwork itself remains unchanged.
When you say "I wish there was an EXPORT GPU preview option," the crucial part is
Your desired look is what is seen on screen, and hopefully that is the key:
You can try to create a screenshot (PNG) of/including the desired GPU preview appearance and use (the relevant part of) that instead of exporting the artwork (to a(nother) raster format in any case), if it is possible to get the desired resolution/image size.
I could screen capture the GPU preview, but typically I need to export for high resoultion, for print. It's frustrating to work on an illustration with nice thick textured lines, then only to discover at export that the lines are really about .5 pixel thinner and with no texture. Here's an example: Image on the left is a screen shot of my artwork, and on the right is the export. I'm using a textured brush to make these lines, to get a vintage look. But when I export, the lines look much more mechanical and smooth. As an illustrator, if I can't export the artwork I see, then why use this application at all?
I can see the difference, and I believe that the randomness of the irregularities is beyond what can be obtained with other means such as the Roughen effect already mentioned.
With a rather low size and high detail you get a thicker appearance, and with multiple applications with different values you can get a certain randomness of irregularity, but hardly enough.
It took an entire day, but I was able to make some textured brushes that gives me the effect I want on export. I've used the roughen effect before and it is a little too modulated and tedious, and prone with errors. I like to see the roughness as I draw, not after. Anyway, it's on my wishlist to have a GPU export option, but until then I have to keep turning off GPU to see what I'm ultimtaly going to end up with.
I was certain that would be the case.
I am afraid that Illy (job description Adobe Illustrator) has no clue about the GPU appearance, but if she can get one, (that part of your) the wishlist can be expressed as (a) feature request(s),
