Printed color coated plate manufacturer

The selection and use of ink for printed color coated plate have strict requirements.The following is a detailed introduction of printing ink by printed color coated plate manufacturer:

1.Ink type

The commonly used ink types for printing printed color coated plate mainly include solvent based ink,water-based ink,and UV curable ink.
1.Solvent based ink:It has the characteristics of fast drying speed,strong adhesion,and good wear resistance,and is widely used in various printing machinery and printing processes,especially suitable for occasions with fast printing speed and high printing accuracy requirements.
2.Water based ink:An environmentally friendly printing ink developed in recent years,which uses water as a solvent instead of traditional organic solvents for printing.It has the advantages of fast drying speed,non-toxic odor during the printing process,and reduced environmental pollution.It is suitable for printing materials such as paper,cardboard,and paper packaging,and is also used in printed color coated plate.

3.UV curable ink:By irradiating with ultraviolet light,the resin forms a solid state within a few seconds.It has the characteristics of fast drying speed,solvent-free,and good light resistance,and is suitable for occasions with fast printing speed and high requirements for printing quality.

2.Ink characteristic requirements

1.Dryness:Ink needs to have an appropriate drying speed to meet the continuous printing requirements of the printing machine.Meanwhile,too fast a drying speed may cause the back of the printed color coated plate to become dirty,while too slow a drying speed may affect printing efficiency and quality.
2.Adhesion:The ink should be able to firmly adhere to the surface of the color coated board without easily peeling or fading.The quality of adhesion directly affects the durability and aesthetics of printed color coated plates.
3.Fineness:The higher the fineness of the ink,the better its adhesion ability,but the cost will also increase accordingly.Delicate ink can present richer color layers and clearer pattern contours.
4.Light and heat resistance:Printed printed color coated plate may be affected by sunlight or high temperature environments during use,so ink needs to have sufficient light and heat resistance to ensure that the printed printed color coated plate do not fade or deform.

5.Environmental friendliness:With the increasing awareness of environmental protection,more and more printing factories are choosing environmentally friendly inks to reduce the harm to the environment and human health.Water based ink and UV curable ink are common environmentally friendly inks.

3.Ink selection and usage precautions

1.Choose ink according to printing needs:Different printing needs also have different requirements for ink.For example,in situations where rapid drying is required,solvent based ink or UV curable ink can be chosen;Water based ink can be chosen for environmentally friendly occasions.
2.Pay attention to the compatibility of ink:When selecting ink,it is necessary to consider its compatibility with the printing machine,substrate,and post-processing technology to ensure the smooth progress of the printing process and the quality of the printed color coated plate.
3.Strictly control the amount of ink used:The amount of ink used directly affects printing costs and quality.Excessive ink may cause problems such as printing printed color coated plate being too thick and difficult to dry;Insufficient ink may affect the color saturation and clarity of printed printed color coated plate.Therefore,it is necessary to strictly control the amount of ink used to ensure that it is within a reasonable range.
4.Pay attention to the storage and preservation of ink:Ink should be stored in a dry,cool,well ventilated place,away from direct sunlight and high temperature environments.At the same time,it is necessary to regularly check the quality and condition of the ink to ensure that it is used within its expiration date.
In summary,the selection and use of ink for printing printed color coated plate need to comprehensively consider multiple aspects such as ink type,characteristic requirements,and selection and use precautions.Only by selecting the appropriate ink and using it correctly can the quality and effect of printed printed color coated plate be ensured.
