Third, the use of methods

1. Before the ink is used, stir the ink evenly.
2. When used, dilute to the proper viscosity with the supporting oil of the withered oil, and mix it before printing on the machine.
3, the amount of varnish, the user can according to the actual use of the situation (such as the adhesion, gloss, color strength of different requirements), increase or decrease the amount of varnish. It is generally recommended to add: The dilution ratio of ink and varnish is: 0.5~1.5.
4, Yinhai brand series regulator ink selection principle:
(1) Quick-drying drying speed, used for printing speed or low-temperature drying;
(2) In general dry type drying speed, it can be used in general;
(3) The slow drying type has a slow drying speed and is generally used for high temperature, hot weather or particularly dry occasions.
5. During the printing process, the shutdown or idle time must not be too long to avoid the ink drying up or crusting in the ink tank. Unused ink and varnish should be poured back into the original packaging, sealed and kept for the next use;
6, if the user has special requirements for the color, the same series of ink can be used in the factory according to the different colors of their own deployment (also by the factory's technical staff to coordinate deployment). However, other columns or other manufacturers' products cannot be used for deployment. Otherwise, the printing quality will be affected or the ink will be scrapped.
7, printing machinery, equipment and tools can use our factory varnish for cleaning.

Fourth, pay attention to matters


1. This product should be stored in a ventilated and dry warehouse, and should be kept away from fire.
2. The production site is not allowed to smoke or contact with fire, and fire extinguishers should be provided.
3, production sites should be kept ventilated.

V. Schedule: Abnormal Situation and Processing Method in Printing Process

Anomalies
the reason
Approach
Printed products are light in color, and the color intensity does not meet the requirements
1. Ink dilution
2. Ink layering
3. Bad ink transfer
1. Add original ink
2. When used, stir the ink
3. Check roll printing ink transfer mechanism
Bad ink drying
1. Direct use of original ink printing or ink transfer has not been added to a small amount, resulting in overprinted prints
2. Slow-drying varnish
3. Humidity or poor drying system during printing
1. Appropriate increase in the amount of ink added 2. Switch to quick-drying varnish
3. Slow down the printing speed, improve the drying system, lengthen the conveyor belt
Printing product adhesion does not meet the requirements
1. Over dilution
2. Substrate has excess oil
3. Too much miscellaneous material is added to the substrate, resulting in a decrease in surface tension. Users have a particularly high requirement for adhesion
1. Add original ink or tackifier
2. Degreasing
3. Add tackifiers or switch to other types of inks
4. Tackifier
Irregular hair on edges
1. Inconsistent pressure between the ink roller and the printing roller
2. Uneven printing plate
3. Ink viscosity is not high
4. Ink on the plate
1. Adjust the pressure between the ink roller and the printing roller
2. Leveling plate
3. Increased ink balance
4. Clean plates and switch to slow-drying varnish
Ink gelatinization
1. Use wrong thinner or other series and ink, varnish oil share 2. Ink exceeds shelf life and deteriorates
3. The temperature is too low (more than -2C)
1. Use the matching varnish
2. Replace ink
3. Thaw with a hot bath
Plate printing ink
1. Use quick-drying varnish
2. Slow printing
3. Long downtime in the middle
1. Switch to slow-drying varnish
2. Improve the speed of printing
3. Clean the plate
Sticky
1. Slow-drying varnish
2. Problems with the drying system
3. Fast printing
1. Switch to slow-drying varnish
2. Improve the drying system
3. High speed printing speed
Ink bucket on ink crust
1. Ink drying is too fast
2. Slow printing
3. The ink head is open
1. Switch to slow-drying varnish
2. Improve the speed of printing
3. The ink is sealed, or the circulation system is added, or the ink is replenished regularly and mixed
Ink cannot be transferred to the printed material or the pattern is shaded
1. Inappropriate solvent
2. Uneven printing plate
3. Inaccurate printing and pressure
4. Ink roller wear
1. Use slow-drying varnish
2. Change to a new plate
3. Adjust ink roller stamping interval
4. Replace the new ink roller
There are small particles after printing
1. Ink uneven
2. After the ink tank dries, there are particulate residues. After the ink is newly added, it is introduced into the ink transfer roller.
3. With wrong thinner or ink, resulting in gelation of the ink
1. Before the machine is on, it must be fully stirred
2. After each printing, it is necessary to clean the ink tank 3. After cleaning the equipment, re-use the same series of ink and high ink oil
Ink precipitated or precipitated in the ink tank, not colored
1. With wrong thinner
2. Thinner and ink are not compatible
3. The mechanical idle time is too long, causing the solvent to evaporate and absorb moisture, making the ink poorly soluble.
1. With new and thinner
2. Use the same series of inks and thinners. Adding slow-drying varnish
Puland inks fade after printing in alkaline fertilizer bags
Pulan ink poor alkali resistance
Use similar colors in the same series, or deploy from the factory
