I wrote a line of text on each page of a swatch book using a Hero 200D pen with Diamine violet ink.

These are FP friendly:

• Pure White 100 text
• Bright White 65 cover
• Natural 80 text
• Ivory 24#
• Light Blue 70 text
• Light Pink 24#
• Willow 70 text
• Light Green 70 text
• Light Gray 70 text
• Bright White Fiber 70 text
• Light Blue Fiber 70 text
• Natural Fiber 70 text.

These are not:

• 100% PC Cool White 100 cover
• Warm White 80 cover

Any chance of showing us examples of the samples in use?
