Tip#55: The secret to printing brilliant uniform colors: using Tone Lock together with K-Lock in MagicPicker
Keep colors bright or dark when rotating Hue° while saving low level of K ink of CMYK – all at once! That lets you find colors on the color wheel within the same dynamic gamut range that look bright when printed! To do that switch on both Tone Lock and K-Lock in MagicPicker – they work together very well! Then rotate Hue° on the color wheel and you will see how MagicPicker adjusts the color so it sustains same perceived brightness and the same K value!
This technique works in Adobe Illustrator & Photoshop CS6, CC, CC2014, CC2015, CS5, CS4 and CS3.
