bad quality export

Postby xenovolcano » Fri Jun 06, 2014 4:42 am

Hello

I did some graphics for a CD cover using a 84 mb .tiff file as the base image and a high-quality font to write over it, yet no matter what I try, i can only generat a low-quality jagged image on inkscape whereas the smaller text is unreadable, and the larger lettering still has jagged edges. this horrible quality shows on the print as well. Sad, because it took over two hours of work to do this. tried to export pdf as well as png with no success.

Any ideas?

thanks,
david

Hello David,

It's a bit unclear from your description.
By exporting the raster part as well to png, you would need to take care at anti-aliasing.
Like leaving the raster image unscaled, setting the exporting area around it, and using 90 dpi for the resolution.
If the image doesn't fit the export area's pixel grid, the result will end up blurred of the anti-aliasing.

Even if clipped for some texture effect on the vector parts.

With the letters, they might be too small and detailed for the export resolution?
I'm not sure, if you can see them jagged in print -meaning you can see pixel sized details-, then maybe the original tiff is not large enough too?
Confusing, 84 MB file is large. Are you using the right printing materials and printer settings?

Large letters as well, hmm.
Can we have a look at it?
