The Thermostar Thermal Plate Structure The Thermostar Thermal Plate has two coatings each with its own unique features. The first layer has a thickness of 1.1nm and is composed of a phenolic resin-type hydrophobic polymer. Its functions are: a. Long print characteristics can be obtained by baking or not baking; b. Excellent developability and coatability. It ensures the balance of water and ink, prevents the dot from increasing, and the layer does not sense light of any wavelength.
The second layer is only sub-micron thick, has a good ink receiving performance, infrared light, strong hydrophobicity, is insoluble in alkaline developer, and can form a physical mask layer that blocks the development of the first layer. The layer contains carbon or With sensitizing dyes, if no sensitization is required, dyes can be added to enhance the contrast.
This version of the structure of simple plate making and coating process is easy to control, the photosensitive plate of the mass production of the difference is very small, only less than ± 0.051gH.
Second, the photosensitive properties of the Thermostar version
The spectral sensitization peaks of this edition are 830~870 nm (diode laser), 1050~1150 nm (solid infrared laser), other ND-YAG 1064 nm or ND-YLE 1053 nm, and there is also Polaroid's newly developed fiber laser 1100. Nm and so on. These plates are fully light-room operated and do not sense visible light nor ultraviolet light.
The absolute sensitivity of the plate is determined by the imaging speed or the pixel dwell time. Its sensitivity is non-reciprocal, and sensitivity is determined by the scanning speed.
The external drum exposer uses a Creo Trendsetter 3244 or Scitex Lotem 830 plate graphic output machine. Its drum speed is slow to improve the platemaking ability. Multi-beam laser technology is used. In this way, the pixels stay longer and the heat loss is greater. In adjacent layers, there is insufficient thermal energy for the latent image.
Www internal drum exposure machine with Agfa's Galico T or gerber Crescent C42/T plate image output machine, single laser beam exposure, high scan speed, short pixel dwell time, ratio of 367 m/s: 32 Ns, under this condition, the laser energy used is sufficient to complete the formation of the latent image.
The resolution of the drum image of the Thermostar version requires about 30 mJ/cm2. In this range, the sensitivity does not depend on the scanning speed. In the low speed range, the sensitivity is related to the scanning speed. With the Creo Trendsetter 3244 exposure, at 15 r/min, approximately 180 mJ/cm2 of exposure is required; at 60/min, approximately 300 mJ/cm2 of exposure is required. The other editions need to be low. The thermal plate that is exposed by the external printing plate graphic output machine can be compared with most other commercial printing plates. As we now understand, the Thermos tar version has all the features of other commercial thermal plates.
Third, the characteristics of the Thermostar version of the resolution and quality characteristics
Wwww, like other thermal plates, has high resolution, but its actual image quality is also determined by the plate format output machine. The Thermostar version shows perfect line reproducibility across the entire range of tones, even with micro-dot FM-screening technology using 2×2dpi 2×2 pixels.
w ww2. Exposure width and processing width
w The exposure and processing widths of the plate are large. This width ensures stable plate-making performance and is consistent with the reproduction quality of plate making. Exposure and processing widths are primarily determined by the optical performance of the image output machine used. This is because the current wet processing thermal technology cannot fully adapt to binary imaging without the need to process the thermal plate by the intended purpose that may be achieved.
. Print width, dot gain, and print length The plate has a good plate latitude. It should be an aluminum support. After exposure and development, the non-image area can be easily removed and the coating on the support surface has high hydrophobicity. In the printing on the machine, the balance of water and ink is good. As a result, the dot increase value of the ink is completely consistent with the value expected by the traditional positive drawing board.
Wwww can use a variety of methods to test the printing process, such as using different types of ink, fountain solution, blankets, and photo paper, etc. In all cases, up to 150,000 printing times and up to 1 million times after baking.
