Pixelation detection and toler
Pixelation detection and tolerance level
Photojunction will show warnings if your images are becoming pixelated while you are designing your album. This guide ensures the best possible printing for your album.
Warnings and tolerance
The pixelation warnings are based on a combination of the high res image size, the aperture size, and the amount of cropping that is applied. For example, if you have a high res image that's 3000 pixels across, and you're printing at 300dpi with no cropping on the image, the aperture can be up to 10 inches across without any problems at all. The tolerance level means that Photojunction will ignore any warnings to x % beyond this figure e.g. a 20% tolerance level in this instance would mean that Photojunction would start giving warnings when the aperture is more than 12 inches across, assuming all other factors remain the same. Cropping the image will reduce the size that the aperture can be before the pixelation warnings come up.
If you're concerned that an image may become pixelated on export, we would recommend doing a test high res export for that layout, as this will allow you to double-check the image as it will be printed.
Photojunction bases the pixelation warnings on the following:
-The pixel width and height of the image.
-The amount of cropping applied to the image.
-The ratio in size between the high res and low res versions of the image. This is because in certain cases (e.g. Remix DIY), there can be several different DPI options to choose from.
We also have a tolerance level that allows for an extra percentage of pixels before giving a warning. The 20% tolerance level is fairly conservative, and it should be possible to increase this to 30-40% without any problems.
The warning icon is refreshed when the Album Layout window is refreshed. This should happen when you recreate the low res proxies, though it can take a while to complete the refresh process.
