Product Description
The offset ink spot color proofing machine is designed and produced by imitating the working principle of printing machines. The proofing machine has adjustable pressure and a wide range of substrates, and is suitable for use in packaging printing production, paper production enterprises, ink production enterprises, scientific research institutions and other departments. Accurately predict the color of ink through standard sampling. By constantly comparing the colors with the standard sample, the correct ink ratio is determined. After the spot color is correctly mixed, it is then mass-produced on the printing machine according to this ratio, turning the color matching work into pre press work.

characteristic:
1. The whole machine adopts microcomputer automatic control, high-definition LCD screen display, and detailed parameter information of each function is displayed on the screen, making the operation more user-friendly and intuitive.
2. Built in three ink blending modes for personalized settings, meeting different operating habits and special situations.
Positioning in series, intermittent engagement, fixed engagement, both time and speed can be freely set (each level can set ink mixing time from 1 to 200 seconds, and speed can be set to high, medium, and low levels).
The soft start function can be set to not move in the middle, reducing uneven color development on the left and right sides and preventing ink flying.
3. Equipped with a high-precision synchronous motor, the interface accurately displays the current color pressure value. With just a simple press, it can automatically adjust to the desired color pressure.
4. Suitable color development pressure can be obtained for different thicknesses of materials, with a wide range of adjustable pressure (negative 1-40, positive 1-80) mm.
5. The color display speed can be pre-set in the mode (with adjustable high, medium, and low speeds).
6. Personalized customization of two-color, three color, and four-color printing rollers is available to fully meet the needs of various practical usage situations, facilitating more intuitive analysis of the comparison and accuracy of current ink color samples.
7. Ordinary ink rollers and UV ink rollers can be selected according to actual needs, covering substrates such as news paper, offset paper, copperplate paper, brochure paper, writing paper, kraft paper, gold card, silver card, etc.
8. In cleaning mode, the metal roller can move separately or move together with the ink roller (cleaning separation, cleaning combination).
9. The cleaning speed is divided into high, medium, and low gears, and can be set at low, medium, and high speeds according to the level of proficiency, making the operation more convenient, safe, and fast.
Advanced Digital Control for Reliable Ink TestingAchieve consistent and repeatable results with the press's digital touch panel, which allows precise adjustments for print layer thickness and speed. The digital LED display ensures real-time status monitoring, making every test accurate, regardless of operator experience. Its rapid response time and high-resolution controls streamline lab workflows and industrial testing.
Versatile and Efficient ProofingDesigned to handle multiple ink types-including offset, UV, and flexo inks-this press is compatible with universal ink testing processes. Its manual feed system accommodates single or multiple specimens, making it suitable for high-throughput applications. With sheet coverage up to 220 mm width and up to 150 sheets per hour, it's optimal for both research and production environments.
Easy Operation and MaintenanceInstallation is as simple as plug and use-there's no need for complex setup or calibration. The quick-release cleaning system minimizes downtime, while industrial-grade rollers and a safety system (emergency stop and overload protection) ensure both durability and user safety. Technical service and calibration support are readily available for peace of mind.
