nullpointer Posted December 7, 2021 Share Posted December 7, 2021 I'm exporting PNG's in AD that will be printed on Amazon t-shirts and I'm curious which resample I should export for best results, bicubic or bilinear? Quote Link to comment Share on other sites More sharing options...

In general bicubic will give slightly better/sharper results than bilinear.

Isn't it better to export and evaluate the results visually? If there was only one right choice, why would the others exist and be used? Why not use Lanczos, for example? So it always depends on the type of content you export.

nullpointer Posted December 7, 2021 Author Share Posted December 7, 2021 I'm not using any photos and everything I do is solid color graphics and occasionally some gradations. Quote Link to comment Share on other sites More sharing options...
David in Яuislip Posted December 7, 2021 Share Posted December 7, 2021 Here's a simple test, a canvas 4000 x 3000px with a linear gradient was exported to 800 x 600 for each resampling algorithm. The results were stacked, each layer set to Difference. If you select any two the screen is black so I suggest that you use nearest neighbour as it's the quickest sampling.afphoto Old Bruce 1 Quote Microsoft Windows 11 Home, Intel i7-1360P 2.20 GHz, 32 GB RAM, 1TB SSD, Intel Iris Xe Affinity Photo - 24/05/20, Affinity Publisher - 06/12/20, KTM Superduke - 27/09/10 Link to comment Share on other sites More sharing options...
nullpointer Posted December 7, 2021 Author Share Posted December 7, 2021 Pretty cool test! I'm not sure I follow the logic. Are you recommending using nearest neighbor? Quote Link to comment Share on other sites More sharing options...

If you stack a couple of images, set the blend mode of the top one to Difference you will see the differences between the two images. If the display is black it indicates that there are no differences, also refer to the histogram. So my example shows that there are no differences between the algorithms in which case use any. Nearest Neighbour is the simplest and quickest so you might as well use that. For a continuous tone image like a photo' I would never use NN, I regard it to be as useless as the bmp file format but in this case going from a vector shape then it works. Try it for yourself with one of your typical images Quote Microsoft Windows 11 Home, Intel i7-1360P 2.20 GHz, 32 GB RAM, 1TB SSD, Intel Iris Xe Affinity Photo - 24/05/20, Affinity Publisher - 06/12/20, KTM Superduke - 27/09/10 Link to comment Share on other sites More sharing options...
