How to keep a high resolution when rasterize

[akdnwhe2k3]

Hi!

I was wondering if I still need to rasterize my line work when I'm working on an exact size of paper that I want print or show.

So I have my drawings on letter paper and whenever I rasterize the line work and export it as png the resolution is still too bad.

It would be nice if I can know what's the best way to save or export the line work to work with photoshop later...

Thanks!

if you're going from AI to PS, it'd be better to not rasterise in AI at all, but place your work into PS as a smart object. then you only need to rasterise it once you know the dimensions you'll be working at.

Thanks for your reply!

So do I only need to rasterize after I'm done with photoshop?

I copied from AI to PS as a smart object and I still feel like the resolution is still same..?

the resolution will be whatever your PS document's resolution is.

You lost me.  Why all the trouble?  Why wouldn't you be able to "print or show" at "exact size"?  Your workflow sounds off.

"So I have my drawings on letter paper and whenever I rasterize the line work and export it as png the resolution is still too bad."

The problem is the highest resolution is 300ppi.  For line work, you need a minimum of 1200ppi @ 100%.  All the more reason to keep the artwork vector.  A possible workaround would be to enlarge a copy of the original artwork to 35"w x 44" h > Export as .tiff @ 300ppi ( grayscale? ).  Then, in Photoshop, reduce back to 8.5w x 11" h @ 1200ppi.

"It would be nice if I can know what's the best way to save or export the line work to work with photoshop later..."

Could you explain why you have to go to Photoshop?  Why rasterize?  Something's missing.

Just on my android

,but don't the  resolution settings go - low 75  - medium 150 - high 300 - other

and under other,  can't you dial the resolution higher than 300ppi eg 1200 ?

Yes, you are correct, Ray.  Forgot about "other".  Just ran a test on a logo, opened in Ai > Export > Other 1200ppi Grayscale.  I then opened the Grayscale file and converted it to bitmap, 1-bit Black and White.  I probably would experiment with both 2540ppi and 5080ppi, just to see what happens.

Maximum res out of Illustrator is 2400ppi.  I ran another test thinking I could input 2540, but Illustrator max'd out at 2400ppi.  So, if I wanted to get a resolution of, say 5080ppi, I'd enlarge the vector artwork around 250%, export at 2400 and resize in Ps 50% to 5080ppi.
