USES
This instrument is designed to examine printability of printing ink, paper roller, blanket, fountain solution and so on .
You can get the dame results as practical printing without any problem.
It is very easy to handle, so you do not need any skilled operator. And also you can evaluate which material has better printability by comparing the specimens to be tested with the known standard, not to express the printability such as printing pressure, speed, ink thickness or surface strength of paper etc. in theoretical figures.
From the practical point of view, it will help you to control the quality and to analyze where the trouble come form in your plant.
You can make a selection of three models to meet your requirement.

FEATURES
Tests are made in a simple operation of transferring ink which thoroughly mixed on the slub, to the paper feed onto the cylinder. The transfer of the ink is made by the rubber roller. Model RI-1 has four units the operation around the cylinder. Accordingly, one complete rotation of the cylinder results in a four-color over printing. The three-color or two-color over printing can be easily performed by dismounting one or two units. Model RI-2 is single color and Model RI-3 is two color.
Mechanism of both model is very simple and easy operation.
- Tests about smoothness, ink receptivity, ink absorbency, picking, fluffing, strike through, show-through and other characteristics of paper.
- Tests about ink characteristics such as color tone mileage, trapping, ink/water relationship offsetting, operation of paper.

Description
- RI-1 has one impression cylinder and four ink transfer units. RI-2 has one impression cylinder and one ink transfer units. RI-3 has one impression cylinder and two ink transfer units.
- Ink transfer unit being equipped with one steel roller and one rubber roller. The surface area of roller is 1,000cm²
- Revolution of each roller is 500rpm.
- Each of the ink transfer units of RI-1 is located at the rigid impression cylinder, which is arranged like a satellite.
- A pair of roller can be simultaneously contacted with or can throw off be cylinder by handle.
- Impression between steel and rubber roller or rubber roller and impression cylinder are adjustable each other precisely.
- Rubber roller can be dismounted from the tester easily and quickly when it is necessary.
- Rubber roller works as a plate roller for the impression cylinder and steel roller functions as vibrator.
- The surface of the impression cylinder is smoothly ground. The cylinder is equipped with paper gripper. It is rotated manually.
