The Presto Hand Opreated Crockmeter is a textile and yarn testing equipment used for testing the transference of color from the surface of one material to another by either wet or dry rubbing. In addition to color transference tests, the crockmeter performs scuffing, wet / dry abrasion, flexing, powdering, dry-cleaning, ink abrasiveness, and other tests. Test conditions are controlled and reproducible through the use of standard pressure and motion.

Specimens are rubbed with dry, standard cotton cloth (Crocking cloth) and again, if applicable, with wet cloth. The staining of the crocking cloths is assessed with a Grey Scale of ISO/BS Std. for staining.

On the crockmeter a pre-cut crocking cloth is mounted on the rubbing finger and is held in place with a spring clip. The finger is 16 mm in diameter and rests on the specimen with a force of 910% N (917.43 Gms). Motion to the finger is given by a Handle, which moves very smoothly on steel movement platform. The required number of cycles are registered on a re- settable counter, which can be easily be set to zero, once the test is complete.

Presto Motorised Crockmeter is used for the determination of color fastness of textile and yarn against rubbing under either dry or wet condition.

Motorized Crockmeter is an advanced version of crockmeter, which is operated by a geared motor. It consists of the main unit having an oscillating arm with a finger. Which rubs over the test specimen under a specified load over the test specimen.

Presto Spectrum ASIA - Color Matching Cabinet, provides standardized and controlled environment for visual assessment of colors. It is suitable for all applications where there is a need to maintain color consistency and quality.
It allows a person to evaluate color samples under different light sources:

• Artificial Day Light (D-65)
• Cool White Light (CWF)
• Tungsten Filament Light (Domestic Light Matching)
• Ultra Violet Black Light (Whites & Fluorescent Dyes)
• TL-84 Light -Triphosphor Fluorescent Light (Point of Sale)

The use of multiple light sources is the only way to detect metamerism -a phenomenon where samples appear to match under one light source but are distinctly different under another.

Spectrum ASIA is a universally preferred choice for faster, closer and accurate color matching.
