用途：

該試驗機設計用於印刷適性的評估測試，包括印刷油墨、紙張、輥輪等等性能評估。

通過模擬測試，用戶可以獲取與實際印刷相同的測試結果，該儀器操作簡便，無須特殊培訓。用戶可以將本機印刷的樣品同採用國際標準印刷的標準試樣直接對比以評估材料印刷適性的好壞，不僅僅表述印刷壓力、速度、墨層厚度或紙張表強等等印刷適性。從實際生產的角度出發，該機將幫助使用者控制產品質量，分析工廠的產品問題來源。

��

特點：

������ 該試驗機的測試過程即為一種將油墨轉印至緊貼於印刷滾筒上的紙張上的簡單印刷操作。油墨轉印過程由橡膠滾輪完成。

������ RI-1型繞印刷滾筒（impression cylinder）一圈有四個印刷單元，滾筒轉一圈完成一個四色印刷。RI-2型為單色印刷，RI-3型為3色印刷。所有型號的印刷機理簡單、操作方便。

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.

1.������������ Tests about smoothness, ink receptivity, ink absorbency, picking, fluffing, strike through, show-through and other characteristics of paper.

2.������������ Tests about ink characteristics such as color tone mileage, trapping, ink/water relationship offsetting, operation of paper.
