When downloading the project as PNG, I have noticed that the DPI of image is 96. I use it for print on demand (Teepublic) and it requires the design to be at least 150 DPI (300 is recommended). So, I have to download the project as SVG then open it in Inkscape and export as PNG with pHYs dpi equal to 300. ---- Note: The "pHYs dpi" enables you to set the value you want and maintaining the image size at the same time. Thank you. ---- Edit (30-APR-2022), I noticed that you can select DPI when you change the unit to "inch" or "mm", but there are three things here: DPI field is not present in "Pixel" unit. I have designs 5000x5500 px and when I changed the unit to "inch" to set the DPI at 300, found that the maximum DPI is 80! While square designs like 1200x1200 can be set to 300 DPI. Image size changes when changing the DPI, so I think it's better to use "pHYs dpi" which lets you export the image with dimensions you want, and at the same time export it in any DPI value.
