label printing proofer inks spot color proofer

Specifications

Seven major functions of Caibang Printability Tester for offset inks, UV ink, UV flexographic printing inks ,labels, hangtags ect.

1. 1.       Spot color proofing

The multi-segment color mixing simulation machine can print color bars of different colors or the same ink color bar of different ink layer thickness at the same time, and can also print new and old ink on the same material for comparison, providing high-efficiency color comparison.

2. Four-color ink testing

It can test color hue, gloss and color concentration of ink, helping to control the quality of printed products basing on control of raw material quality.

3. Sample printing for pre-printing review by customers

It can print simple color bar for pre-printing review or filing by customers.

4. Testing color change of dry and wet ink

It can show required spot color ink color bar, and forecast the color hue after drying of the spot color (for example, purple and dark blue may turn reddish after drying, and this can be solved before printing).

5. When used together with a quantifier, it can forecast the consumption quantity of spot color ink, helping to greatly reduce residual ink waste and stock. It can also forecast ink transfer quantity and ink layer thickness.

6. Data-based management

When used together with spectral density meter, it can provide a data report on the color bar measured (Lab value).

7. When used together with other related instruments, it can forecast wear resistance, drying time, light resistance, heat resistance and other features of ink.

Characteristics of Caibang color mixing simulation machine

1. When used together with a quantifier, it provides high repeatability.

2. It can print on various materials, including book paper, coated paper, grey board, offset printing paper and tinplate.

3. Safe and simple operation.

4. Easy cleaning and maintenance. 

Technical parameters:

Ink uniforming mode:

1. The ink uniforming speed can be switched between automatic regulation and manual regulation, meeting different operation habits and various special use conditions.

2. As for chain movement, no-chain-movement soft startup mode with middle positioning can be set, so that left-right uneven color presentation and ink misting can be reduced and the precision of color presentation can be improved.  

3. Time setting for four-section ink uniforming manner (0-200 seconds settable for each section). Any ink uniforming manner can be set at will, including chain movement middle positioning, intermittent closing, fixed closing and automatic speed changing, providing better accuracy and convenience.

Ink uniforming pressure:

Automatic regulation basing on wearing of the printing roller or the error between new and old printing roller.

Color presentation pressure: Automatic regulation basing on thickness of the color presentation material (-1~+1mm), providing better precision and convenience.

Color presentation effect: A 10mm secondary color presentation area of light color is set, so that user can compare the difference between two colors more accurately and visually at the time of ink comparison (See the color sample picture of NB229T).

Cleaning: No chain movement of the metal roller under cleaning mode, providing higher safety and convenience.

Printing roller: Two-use roller for common and UV printing as standard configuration.
