basic requirements for the identification of advanced electronic color separators

I. applicable object

operators engaged in electronic color separators

II. Application conditions

1. After obtaining the intermediate "technical grade certificate" of this type of work, those who meet one of the following conditions:

(1) this type of work has worked continuously for four years

(2) Bachelor degree, major in printing technology (or related majors), and have worked in this type of work for more than two years

2. Healthy, without color blindness and color weakness

III. examiner

1. theoretical knowledge examination: every 20 candidates are equipped with one invigilator (20:1), and the invigilator shall not be less than 2

2. Operation skill assessment; Every five candidates shall be equipped with one assessor (5:1), and there shall be no less than two assessors

IV. identification method and time

1. Theoretical knowledge examination: closed book examination is required. The proportion of question type allocation is: fill in the blank 20%, multiple-choice 20%. If the accuracy of the strain gauge is not high, or the anti-aging ability of the glue used to fix the strain gauge is not good, or the material of the sensor is not good, it will affect the accuracy and service life of the sensor. Calculation questions are 10%, short answer questions are 30%, and narrative questions are 20%. The examination time is 120 minutes. The full score is 100 points, and 60 points pass

2. operation skill assessment: actual operation is required, and the assessment time is 60 minutes (excluding proofing). The full score is 100 points, and 60 points pass

v. requirements for identification tools and equipment

1.25 times or more magnifying glass

2. One black-and-white densimeter (measurable density and percentage of points)

3. One electronic color separation machine (with original and recording film)

4. One automatic film developer

5. When evaluating the quality of color separations, it is necessary to configure proofing equipment
