TS Doctor Blade Chart

Accessories offered in support of excellent printing quality.

One Touch Doctor Holder

For easy installation of doctor blades

Secured by one pin, eliminates the need for multiple bolts, and reduces mounting errors and down time
The surface of this blade holder is specially treated with a scratch and stain-resistant solution which also reduces the adhesion of excess sink and makes for easier cleaning

How to Install

Single lever installation and reinstallation eliminates the need for bolting, doctor blade measurement, and back up plate adjustment. The shape is simplified for easy cleaning. We can customize this blade holder per your request to optimize it for your environment.

To set the doctor blade and back up plate, position them according to the positioning pin shown in the above center.

Locking down the lever secures the doctor blade and holder firmly in place.

TS Backup Plate

Promotes even ink scraping pressure and reduces printings defects

The backup plate houses the doctor blade in the holder, all of which forms one unit scraping excess ink off the cylinder. In addition to being able to change the thickness and height, adding plating also has a rust preventive effect.

How to Install

A backup plate with warps and bends unevenly distributes blade pressure which distorts contact with the cylinder and shortens blade life

Our back up plates are excellent not only for blade stability but also for easy blade mounting. A TS Doctor Blade mounted in our blade holder is the ideal setup that ensures even blade to cylinder contact

Please use the high-precision TS Doctor Blade together with the high-precision TS Backup Plate.
