Overview
JPT-8 Ink Proofer is a liquid crystal display, numerical control motor drive, integrated control system equipment, through the timing belt to drive the plate roller spindle mechanism operation. All control parameters and measurement data can be displayed and adjusted in real time, and has reliable accuracy repeability positioning function. The equipment is mainly used to realize the three functions of color scheme, proofing, and get the manuscript ready. It aims to solve the waste of inks color scheme, use the mixture ratio of old and new inks, deal with the old ink in stock, and overcome the inconvenience of traditional machine proofing.
Features
1. Wide range of substrates, suitable for gravure printing, Encasement, inks enterprises.
2, can detect inks Hue, Gloss, color concentration.
3. Simple color bars can be made for pre-press approval or purchase inspection by customers.
4. Spot Color inks can be displayed, and the Hue after drying can be observed after natural drying.
5. When used with inks Basis Weight meter, it can predict the usage of Spot Color inks, reduce residual ink loss and warehouse accumulation.
6, with Spectroscopic Density Meter for color detection, can be measured color bar data report (Lab value).
7. With relevant instruments, it can predict the characteristics of inks Abrasion Resistance, fading, transfer, light resistance and heat resistance.
Principle
The equipment drives the spindle swirl/spin of the plate roller through a numerical control motor to perform inks proofing on the substrate. The operator can set and control parameters such as speed and swirl/spin number through the LCD screen to display color blocks, color samples and patterns with different color ratios. With detection instruments such as spectroscopic Density Meter, the proofing color strips can be measured and analyzed digitally to achieve accurate color scheme and effect evaluation.
Applications
Plastic film printing, decorative paper gravure plate, printing and dyeing, printing iron, gravure printing process, inks production enterprise, inks Agency, plate making factory
Steps
1. Prepare substrates and inks.
2. Set parameters such as speed, swirl/spin number through the LCD screen.
3. Start the equipment for proofing and display color blocks or bars.
4. After the color bar is naturally dried, observe the Color effect.
5. Cooperate with spectroscopic Density Meter and other instruments to measure color bar data (such as Lab value).
6, according to the measurement results and master standards comparison, fine deployment.
Notice
• The working environment is recommended to be within the range of 10 ° C -35 ° C, and the relative humidity is not more than 80%.
• Power frequency of the equipment is 220V +/- 10%, to ensure stable power supply.
• Please pay attention to safety during operation and avoid contact with moving parts.
• Choose the appropriate rubber roller material according to your needs (such as EPDM silicone roller/polyurethane, etc.).
• After proofing, the color strips need to be naturally dried to accurately observe the final Hue.
• When using with related instruments, please follow the instrument operating specifications.
