Kodak Tengger Sonora XP / News print-free plate
What is no-flush?
No-rinsing means that it can be printed directly on the machine without the need for chemical development or plate-making equipment. True no-rinse printing plates, such as Tengger Sonora XP and Sonora News printing plates, are pre-pressed and printed in two steps.
The advantages of no-print plates:
Reduce operating costs and reduce environmental impact.
No need to maintain and operate the washing machine, reducing the burden.
Reduce the pressure of waste developer disposal.
Simplify plate making.
Improve operating efficiency and strengthen process control.
Make printers more environmentally friendly.
In all other respects, the Tengger Sonora XP and Sonora News plates are comparable to the quality of traditional thermal CTP plates.
Prepress performance:
The Sonora XP / News printing plate is a negative (writing image) printing plate.
There is no ablation, so no debris removal system is needed.
Mainstream imaging capabilities:
Can quickly image on the fastest CTP system to increase productivity:
150Mj / cm2, on Kodak plate-making machine, formula shaped spot technology
175Mj / cm2 on the Kodak Achieve plate-making machine
150-210Mj / cm2 depends on the type, configuration and resolution of the third-party plate-making machine.
Mainstream printing quality: 1-99% @ 200lpi, and 20-micron Fangjiajia screen (on Kodak plate-making machine, formula-shaped light spot technology).
Sonora XP / News can image on various Heidelberg Suprasetter and Topsetter platesetters.
Sonora XP / News can be imaged on various Japanese screen-making platesetters.
Kodak prepress settings:
Tengger Sonora XP / News printing plates are fully suitable for most of the automatic plate loading devices.
Technical Overview: Installation of Tengri plate on printing press
The Sonora printing plate is installed like any other printing plate.
Can work with manual and automatic publishing systems.
The image contrast is strong. It can read the font size of 10pt., Which is convenient to distinguish the drum.
Technical Overview: Press Startup
Apply a dampening stick and ink roller to apply dampening fluid and ink to the entire printing plate.
The fountain solution allows physical removal of the coating in non-graphic areas.
The shear force and viscosity of the ink transfer the unimaged coating to the blanket.
Transfer the unimaged coating from the printing plate to the blanket by purely physical action.
This is a physical effect, not a chemical reaction, which will meet the requirements of a wide range of printing press chemicals and printing press setup conditions, and eliminate the changing factors associated with traditional wet processing systems.
Finally, the input paper is imported, and the coating is transferred from the ink on the blanket to the first few sheets of paper and taken away, without causing pollution to the ink and the wetting system.
Usually the background will be clean after 5-10 sheets.
The pre-print time on the web is equal to, or slightly less than that of the wet processing plate.
Registration and color adjustment are the same as any other printing plate.
Storage Conditions:
Both plate preservation and prepress area should be maintained under controlled conditions.
The ideal operating and storage conditions are as follows:
Temperature: 20-25 ° C
Humidity: 30-70% RH
Illumination: white light = 1 hour
UV isolation = 8 hours
Yellow light = 24 hours
Expand the application of Tengger Plate in the printing business:
First use Sonora XP to print jobs that do not require color correction. Check whether Sonora is compatible with the customer's existing press conditions (good performance on the machine, no blind spots / scum, acceptable yield, etc.).
If Sonora works well with existing presses, run a color correction curve for typical jobs to optimize Sonora's colors.
Kodak can help customers set up production profiles (specific paper, inks, printing presses and printing chemicals) to match the currently used printing plates.
Kodak recommends starting with short-run printing to help customers gain confidence in using Sonora in terms of productivity, processing, storage, and printing performance (onboard performance / pre-printing, yield, etc.).
Gradually increase the printing volume of the job, and expand Sonora's application to more challenging environments (such as UV or FM printing jobs) when needed.
With the increase in printing experience, end users will find that Sonora is a true print-free printing quality comparable to the development of thermal CTP plate ... and has the advantages of cost and environmental protection.
Possible obstacles and solutions:
Customers need to adapt to:
Set the color optimization curve
It only needs to be carried out once. The performance and stability of Tengri plates will be consistent across batches.
Plate processing-preservation and white light environment
Simple, low-cost preventive measures, such as saving the printing plate in a used plate box, or inserting backing paper in two printing plates.
No need to measure plates for process control
Sonora is rinse-free, and no inspection is required after rinsing because there are no variable platesetters or chemical potions.
Overcoming misunderstandings on the printing press:
Competitive statement that Sonora will not contaminate the press during the on-press printing stage. As we have seen, in the pre-printing stage the emulsion layer of the printing plate is taken to the blanket by the ink and taken away by the first few sheets.
Previous experience with no-rinse or simple-rinse
Sonora rinse-free plates have many advantages over competitive rinse-free or simple rinse plates, such as longer yields, longer image stability, no special fountain solution, and no rinse steps.
Resistance in the printing shop
Power problems in the prepress / printing workshop
Willingness to change
Competitive printing plate
When one printing does not work, set up multiple printing machines
The technological advantages and reduced operating costs brought by Sonora are extremely attractive to any enterprise. In order to realize these advantages and reduce costs, management needs to provide support and promote the transformation of rinse-free, creating sustainable environmental solutions through Sonora.
to sum up:
The Tengger Sonora XP / News thermal CTP printing plate is a true processing-free printing plate, which only needs 2 steps to be printed on the machine.
Tengger's Sonora plate will bring a lot of advantages:
Reduce operating costs and reduce environmental impact.
There is no need to run the processor and process chemicals, reducing the burden.
Make printers more environmentally friendly
Simplify the plate making and improve the operating efficiency.
In printing, the resolution and yield of Sonora plates are similar to traditional processing plates.
Compared with competitive no-rinse printing plates and simple processing-type printing plates, Tengri plates have quantifiable advantages.
With experience, end customers will soon realize the advantages of Tengri plates, such as performance, cost and environmental advantages.
