Abstract
The invention discloses a method for detecting developing tolerance of a presensitized plate (PS) product, which comprises the following steps that: UGRA step-wedge is firstly used as a tool, and a best developing condition (including concentration of developing liquid, developing temperature and developing time) of a product is found to be used as standard development; standard exposure is carried out for the product; when the developing concentration is adjusted to 1.5 times to 2 times the standard developing concentration, strong developing is executed; and when the developing concentration is adjusted to 0.4 times to 0.6 times the standard developing concentration, weak developing is executed. The method is simple to operate, performance of the product can be rapidly and directly detected, reference can be provided to the adjustment of the production process, the operating tolerance can be improved, the adaptability of the product can be improved, and the product performance can be optimized.
Description
Technical field
The invention belongs to PS version detection range, be specifically related to a kind of detection method of PS version product development tolerance.
Background technology
Often because the development tolerance of PS version is not high, printmaker's operant level differs the PS version in plate making, and the power of developer solution often impacts the plate-making result, makes printing quality not reach requirement.Along with market competition; The client is more and more stricter to the requirement of printing, and it is far from being enough that many enterprises require only to be up to state standards, and the waste of PS version can not be ignored in the material consumption of printing process; Therefore; Improving the development tolerance of PS version, improve operational suitability, is an important indicator of PS version.
Summary of the invention
The technical matters that the present invention will solve:, provide a kind of simple to operate, testing result directly perceived, detection method that can fast detecting PS version product development tolerance in order to overcome the deficiency of PS version Performance Detection.
Technical scheme of the present invention:
A kind of detection method of PS version product development tolerance may further comprise the steps:
(1) example edition is made: get PS version product to be measured; PS version product is cut into the rectangle example edition; Find the best development conditions of product earlier with the Wu Gela step-wedge, as the standard development conditions, the standard development conditions comprises standard developer concentration, standard development time, standard development temperature with this condition; Cut two again with the identical test example edition of example edition size, for use;
(2) standard exposure: two test example editions are put together, on the test example edition, put the Wu Gela step-wedge respectively, carry out standard exposure simultaneously;
(3) develop: respectively the test example edition after the exposure is developed by force and weak development, develop by force respectively and weak development according to the standard development conditions that obtains; During strong the development, be adjusted to solution level 1.5-2 times of standard developer concentration; During weak the development, be adjusted to solution level 0.4-0.6 times of standard developer concentration;
(4) flushing: the test example edition water after will developing is rinsed well, and uses drier;
(5) judge: the test example edition version backbone of weak development is clean, does not have residual chromatograph, and it is qualified to be judged as; Part is colour-fast on the spot for the strong test example edition that develops, and netting twine does not break with interior at 20 μ, and it is qualified to be judged as.
The specification of said rectangle example edition is 20cm * 10cm; Solution level is 1.5 times of standard developer concentration during said strong develop; Solution level is 0.4 times of standard developer concentration during weak the development.
Detection method of the present invention has the following advantages:
(1) simple to operate, convenient, do not need special instrument and equipment, quick and precisely the testing product performance only needs 10-20min detection time;
(2) testing result is intuitive, clear, is easy to judge;
(3) be widely used, can be used to understand and contrast the performance of different product, can also foundation be provided as being provided with and adjusting production technology.
(4) improve the operation tolerance, improve the adaptability of product and optimize properties of product.

Embodiment
Embodiment 1: referring to Fig. 1-Fig. 7, a kind of PS version product development tolerance detection method comprises the steps:
(1) example edition is made: get the example edition that version on the production line cuts written treaty 20cm * 10cm, on PS version printer, find the standard development conditions with the Wu Gela step-wedge: developed concentration 1:6 (developer solution: water, volume ratio), 24 ℃ of development temperatures, development time 30 seconds; Cut two again with the identical test example edition of example edition size, for use;
(2) standard exposure: two test example editions are put together, on the test example edition, put the Wu Gela step-wedge respectively, it is 40 seconds that the time shutter is set, and carries out standard exposure simultaneously;
(3) develop: respectively the test example edition after the exposure is developed by force and weak development, if the concentration of standard developer is that (developer solution: the volume ratio of water), the so strong solution level that develops is set to 1:4 to 1:6; The weak solution level that develops is set to 1:10; Development time is 30 seconds, and development temperature is controlled at 24 ℃;
(4) flushing: the test example edition water after will developing is rinsed well, and uses drier;
(5) judge: the test example edition version backbone of the weak development that obtains is clean, does not have residual chromatograph, and it is qualified to be judged as; Part is colour-fast on the spot for the strong test example edition that develops, step f5, and netting twine 20 μ do not break, site 3-99%, it is qualified to be judged as.
If strong develop, weak development is defective, can be through improving the photoresists performance, methods such as adjustment production technology improve the development tolerance of plate.
