Computer to Plate (CTP) system that produces conventional offset plates of laser quality (175 lpi), plate sizes up to 91 × 150 cm, low cost consumables (typical price $6,5–7,8/sqm). Proven in the field by its successfull application in many printshops.
StudioRIP DTP 24/36 is a CTP (Computer to Plate) system that uses an inkjet printer for producing offset plates. Unlike most inkjet CTP systems, the plates produced by the DTP system are conventional UV plates that look and behave in the same way as any film masked conventional plate does, but its costs are much smaller (similar to thermal CTP costs). Similarly, the cost of the new, warranty covered equipment is a fraction of a laser CTP's price. Although the DTP plates are conventional, they have an additional inkjet coating (similar to what photo papers have) applied in the factory over the photosensitive layer. The DTP plates are available for sale from local StudioRIP dealers, from StudioRIP SRL, or for dealers directly from StudioRIP’s Chinese representative.
The production process is as follows:
Obtain the conventional plates with inkjet coating from your local dealer (or from StudioRIP SRL). The plates come in sealed boxes from the factory.
Align the plate on the front tray to the 3 positioning pins which are automatically activated by the sensors when the plate has the proper position, then let the printer load the plate.
The printer writes the image with black ink in about 7 minutes for a 510 × 400 mm plate (larger plates print in proportionally more time).
The printed plate is exposed by the UV LEDs in the upper drawer, the exposure time being controlled by the system.
Place the plate into the vertical washing tank of the plate processor using the plate holder frame. The ink and the coating are washed off by the running water. The plates can also be washed in a conventional plate washer under a jet of water.
Move the washed plate into the developer tank, where the chemicals are recirculated.
Move the processed plate into the washing tank again.
Finally move the plate into the drying slot. All processing stages are controlled by the system.
The plate can be used by the printing press. It will behave like any other conventional plate.
