What do I learn in this video?

I learn how to properly prepare an image file in Photoshop for wallPen printing, including color mode, resolution, layers, and exporting as TIFF.

Why is this step important?

Only correctly prepared files ensure the highest print quality and prevent color issues.

What should I remember?

Convert the image to CMYK and 8-bit, scale to 300 dpi, flatten all layers, and save as a TIFF with LZW compression.
