Trouble scaling up my work with gradient grain textures

[mikoybnz]

HI everyone!

Im currently wrapping up a personal project of mine and came across an issue. When i try to scale up my entire work from 4x6 to 18x24, the grain effects became smoother, which i dont like. The first picture below is the 4x6 and the second is scaled up to 18x24

Is there a way for me to retain the texture quality from the first picture when scaling up to sizes such as 18x24? I really want that grainy, dirty and noisy look to it and im planning on making art prints out of this. Any suggestions?

I appreciate any help!

When you scale an image you can choose whether or not to Scale the strokes and effects. This can be changed either in the Preferences or in the Transform panel. Try changing the settings to see if this achieves what you want. Lovely image BTW 🙂

I will try that. Im glad you like the picture!

Another way, make a duplicate of the file you want to enlarge, open it , scale it up

and go

Effect > Document Raster Effects Settings

and lower that, Options lets you dial in values

I think this solution only works if your end product is lowress. 

I have this image (wip) which is about one meter wide when printed. To borders of "grained" objects way too low resolution for that. 

Also the Grain gets pixalated, but that could be torelabe..

I appreciate the suggestions guys, will try them once i get home from work!

Nothing happened when i played around with the transform panel, but lowering the ppi through document raster effect settings worked!

Thank you guys for helping!!
