551PF COLORPRO PANTONE MIXING SYSTEM (with Booster Colours) Excalibur’s 551 PF ColorPro is a high-opacity color mixing system that produces simulated Pantone® colours, and custom shades. It consists of 11 standard ready-for-use colors and five additional components called Boosters. Booster Colours are very intense shades of Yellow, Red, Blue and Green. When added in increments between 5%-40% they will increase the brightness and color accuracy of specific colours. Most generally the colors in the 551PF mixing formulas that need boosting are any colours that do not contain white. They generally can be found in the three colours located in the center of each page in the Pantone® “C” Formula Guide. All Pantone® colour formulas contained in the ColorPro Software that will benefit in accuracy with the addition of Booster Colours are presently being updated and added to the software as they are formulated.
Software: ColorPro Software may be used to mix all Pantone© C colours and any special mixed colour.

Mixing: For the most accurate color reproductions use the Excalibur ColorPro Software and carefully weigh out the formula with a digital gram scale that weighs accurately in 0.1 gram increments. Mix thoroughly and test color accuracy by printing a test print with the same size screen mesh and fabric color of the print run. Color accuracy should be evaluated by printing through same mesh size on like substrate after complete curing. Crock testing should be done no sooner than 72 hours after curing. After mixing ink color if finished mixture is not bright enough, add 5%-20% of 551PF Booster Color to achieve a brighter, more vivid color.
Gel Temperature: Ink will gel on surface at 240° F (116° C).
Curing: When correct proportions of pigments are mixed into the appropriate Excalibur Mixing Base the ink will cure when entire ink film reaches 320° F. (160° C).
Mesh: Mesh size will be determined after consideration of artwork and desired end result of decoration.
Stencil: Any emulsion or film that produces a stencil compatible with plastisol ink is recommended.
Modification: Do not add Curable Reducer 501PF until viscosity is evaluated after thoroughly stirring mixed ink. Although 501PF Curable Reducer is balanced and any amount added will not affect cure characteristics of ink too much Curable Reducer 501 can affect opacity, color strength and ink-film strength.
Squeegee: 70 durometer or 90/70/90 triple durometer blades are recommended.
Clean-up: Enviro Series 2000 Green or Enviro Series TR Blend.
Colours: Yellow G/S, Yellow R/S, Red Y/S, Red B/S, Fluorescent Magenta, Violet, Blue B/S, Blue R/S, Green, Black, White, Booster Yellow, Booster Red Y/S, Booster Red B/S, Booster Blue and Booster Green.
