Hello everyone,

I have been trying to upload a new logo. It has the correct dimensions and the quality of the jpg are at the maximum setting. Whenever I upload a new logo to shapeways, the new logo has artifacts and deqrades in quality greatly. I have tried multiple methods and cannot figure out a solution. Any suggestions or help would be much appreciated.

index.php?t=getfile&id=4650&private=0

It's an old issue - after some "Trial and error" i found out that
if you upload a 1600X1000 resolution pics they will display correctly without artifacts.

Check out my shop's pics - all clean and vivid.

Kris,

Yesterday i uploaded a new design, a full color Pencil Holder and found out that pictures with red in it aren't showing good even with my 1600X1000 resolution trick....

So shapeways tech guys should look into it - something to do with parsing and resizing a pic.


Cheers,

Another alternative, of course, would be to allow users to upload other image types, especially PNGs. JPEGs are great for for photographic-type images, with smooth transitions of colour, but can often produce artifacts in graphic images with lots of flat areas of colour.
