DAIHAN INK CO.,LTD COS offset ink Descriptions Improvement in emulsification on the printing press (COS,COL,COH)
To prevent contamination by fountain solution more stable pigmentand materials against emulsification have been used.
This new formula has attributed to improvement of printing performance against emulsification and keep the printed substrate clean.
Improvement of setting and drying time (COH)
Newly application of high performing resin has kept high gloss and helped improvement of shortening setting and drying time.
Fast printing of reverse side by improvement of setting and drying time betters printing efficiency.
Prevention of paper dust (COH)
Improved printing performance by using of updated materials can keep better stability on the printing press and keep consistent flow in high speed printing.These excellent printing characteristic guaranty high quality printing job and help to prevent paper dust during printing process.
