The difference between the flushed strip index and the marked value is within the action range, which means that the flushing is correct and can be washed. The difference exceeds the action range and is indicated as a warning area, which indicates that the process control personnel should take timely and targeted actions to adjust the replenishment amount, liquid temperature, stirring equipment status, etc. until the flushing index returns to normal. If the difference exceeds the control range, it indicates flushing control, and flushing is not allowed. The washing process and equipment status must be changed immediately. The difference between the control range and the flushing process should be comprehensive and accurate. For the unqualified color films sold on the market, the color printing officials should set up special specifications for each brand of color films on the color printing machine, and if the color film set is replaced or the color developing company adjusts the special channel, the color negative film of the same brand standard should reach the specified 4 levels on the color printing track corresponding to the color film brand, which shows the balanced density, color noise rate and exposure limit of the same channel.

The control films should be determined to be qualified products with a validity period of (see Appendix A for the control contract)
4.1 Control strip washing and single sensitivity determination
4.1.1 For more details, take out the control strip and determine the type of control strip based on actual experience. Take the control strip out of the freezer and let it stand for about 30 minutes to reach room temperature. In all cases, the operator should put on gloves, tie them up and tape them, and glue the edges of the strips to prevent fingerprints or damage to the emulsion surface of the control strips. The control strips should be placed in the packaging and stored at room temperature. The remaining control strips should be packed and put back in the refrigerator as soon as possible. After the work is completed, the remaining strips should be used to prevent the strips from being scratched or contaminated. After use, the operator should store the reference strips in the bag.
4..2 control to recording washing
When the color film automatic developing machine is installed, the operator puts the color negative film control strip in the color material spray meeting at the spray bag point, and cuts off the 2I left film. After confirming the washing process, when the liquid temperature of the developing machine reaches the requirements of the developing process, the strip can be washed and inspected. For the color enlargement machine, for the EP2RA-4 series and the obtained processing technology, the color photo paper pad strip is used respectively. The operator puts the color scan paper strip in the air of the film enlargement machine control strip, sticks the side guide tape, and adjusts the color machine without the control box according to the actual situation. When the liquid temperature of the color enlargement process reaches these requirements, the strip can be washed and inspected. 4.1.3 Density measurement of control strips

(Reminder)
Color negative film and color paper processing control strips Color negative film control strips and color paper control strips are used to monitor the working status of color negative film and color paper. The control method is the internationally common method for monitoring the processing quality of the tray. Each color negative film and color core paper should be made by a brand manufacturer: the color negative film production mainly includes five density blocks, namely the minimum inspection block, low density block, commercial density block, high density block and yellow density block. Color paper control strips mainly include four density blocks, bright small density block, low density light, high protein block, sensitive large curtain density block. The control strips indicate the appropriate month's washing process and number. Each batch of strips consists of a standard strip, a control strip with a certain number of calibration data from the batch state, and the standard strips and control strips are made of the same (shaft) material. The standard strips are made by the light-making enterprise under standard conditions and washed under standard washing conditions. The control strips are only lit under standard conditions, and are used to test whether the washing process of the washing department is normal. The washing factory's technical controller uses the standard method used for the production process: the method specified in the batch is used to select the processing plan., first calculate the density value of each density block, and then calculate the calibration value according to the calibration factor to get the standard value of this batch of control strips. After scanning, measure the color value of each density block that has been washed and processed, calculate the difference between the control strip parameter value and the standard, and make a judgment after development. Each batch of control strips is packaged in one package, and the strips are sealed with a broken package and packed in a light-proof package. They should be stored in a refrigerator below 18°C and should be used within the validity period.

Appendix B
(Appendix of prompts)
Color negative film standard film (blue eye)
Standard film (cow laser film) is an essential material for the setting and inspection of the photo enlarger: a certain crystal barrier of the color negative film of the color enlarger must be used to make the standard film of the brand of color negative film set quickly. The standard negative film for photographing objects is the medium gray plate, among which the color plates, figures and objects are mainly medium plates. The standard negative films of the Yurong brand color negative film include: a) standard negative film, that is, three levels of noise negative (U film), three levels of warm light positive film (N film), three levels of excessive light negative (B film), and three levels of base negative (C film). The operator can use a densitometer to measure the density value of the reference plate as the reference value, and compare it with the density value of the enlarged sample. The base photo can also be compared with the enlarged sample by the day method to calibrate the difference. The reference film is a blue film produced under the standard color enlargement state. e) Check the instruction manual.
There are two ways to process standard negatives and reference photos: a) The film production unit processes under standard conditions; h) The film production unit provides a set of unprocessed standard negatives to the color printing shop, which processes under standard conditions. The operator can choose one of the standard negatives according to the actual situation. Regardless of the method, the operator should first use the standardized processing liquid to process under standard processing conditions in the enlarger. If the standard negatives are not accurately processed, they should be stored in a light-proof, refrigerated glass package. The standard negatives should be protected from scratches and stains when used. The validity period of the standard negatives is generally three films. When the frequency is adjusted, the operator shall select the printer and the standard film according to the instructions, and the basic process is as follows: a) Use the positive negative film for standard positioning. When the density of the middle gray plate of the printed photo is compared with the density of the middle point plate of the reference photo of the brand standard negative film, the channel is set. The flow is as follows: a) The middle plate of the second plate of the film and the sample of the negative film enlargement must meet the requirements of the standard. The positioning is completed. b) The color printing shop can make fine adjustments to the channel according to the preferences of customers in the business area, the four seasons and other conditions. For each calibration, use a certain brand of color negative film to print (N) photos of the brand standard negative, compare them with the reference photos after washing, and report the comparison results. Then print (N) photos to achieve the standard.
