Whatever your use of film, the Ihara T500 will enable you to check for proper exposure even with the highest density films up to 6.0D, ensure the development process is clean with no fogging, and measure tints accurately. Look no further than the Ihara T500 - you won' find better value or a more accurate instrument!

Many printing plates are still produced from film and for general quality control we offer the Ihara T500 Transmission Densitometer.

If something goes wrong with your plates, you need to find out what has gone wrong, and whether there is a problem with the film. You therefore need to be able to measure your film, and for this the T500 is ideal. It has the ability to measure high densities and to high accuracy to check proper exposure, and clear areas for fogging to ensure proper development. It can measure both tints on film, so you can see where dot gain errors have occurred.

Used with either the Ihara R720 or R730 Reflection Densitometers with plate reading option, you will have the ability to check the process right through from film exposure to ink on paper.
