Thank you for your review and for sharing your feedback. We are sorry to hear about your disappointment that the colors on your cards came out a bit darker than you had anticipated. You've highlighted a very common and important challenge in the printing world. It’s not technically just about the brightness of the artwork, but rather the difference in color profiles between screens and printers. Digital screens use a bright, light-based RGB (Red, Green, Blue) color profile, which can show very vibrant colors. Our printing process, however, uses an ink-based CMYK (Cyan, Magenta, Yellow, Black) color profile. When a design is converted from RGB to CMYK for print, colors can often appear darker or more muted. However, we absolutely want to look into this for you and see how we can help. To help us investigate the extent of the color shift on your specific order, could you please share a few photos of the cards you received? We appreciate you bringing this to our attention and look forward to the opportunity to resolve this for you.
