Notes
What happens when Printify enhances a low-resolution file
Most platform guides frame low resolution as a rejection risk. On Printify it is not a rejection risk at all, and that is worse.
The upload does not stop you
Printify documents a recommended 300 DPI, dropping to 120–150 DPI for large-format items such as leggings, blankets and tapestries. What it does not document is a threshold at which a file is refused — because low-resolution files are not refused. They are automatically enhanced before the order goes to production.
You also lose control of the result
Whatever the enhancement does — sharpening, interpolation, or something more elaborate — it is applied without your review. Two designs with the same nominal resolution can come out differently depending on their content, and you have no opportunity to compare, reject, or adjust. The only way to control the printed result is to supply a file that does not need enhancing.
There is a second layer to this
Printify is a network of print providers, and dimensions are decided by the product and the provider, not by the platform. That means there is no single "Printify size" to design to — anyone quoting one has copied it from a different platform. Prepare at 300 DPI across whatever print area the chosen provider states, and check the product's own template before a launch that matters.
Frequently asked questions
So what resolution should I actually use?
300 DPI across the print area of the specific product you are publishing. For large-format items the documented floor drops to 120–150 DPI, but designing to the higher number costs nothing and keeps the same file usable across products.
Can I turn the enhancement off?
Not as a setting you control. The practical way to avoid it is to supply a file that already meets the resolution the product needs, so there is nothing for the enhancement to do.
