Blue vs Purple
Exercise caution when creating blue hues for printing. The spectrum of colors achievable in CMYK is notably narrower than the RGB spectrum visible on a typical monitor. Consequently, when a file is converted to CMYK for printing, there's a risk of color shifts and a reduction in vibrancy.
If we notice that your blue might turn purple during printing, we'll request a color adjustment, which could lead to delays. Our goal is to ensure you achieve the results you're aiming for. However, given the subjective nature of color perception, we might not always detect such issues. Therefore, we advise you to adhere to the following guidelines, especially if you're uncertain.
For instance, many vibrant blues in RGB (the color mode used by monitors) often transform into purple hues in CMYK, as they fall beyond the CMYK color gamut. Instead of striving to replicate these bright blues, consider utilizing alternative blue blends more suitable for CMYK. It's important to remember to create your files in CMYK rather than RGB.
