Shooting color-changing target paper and manufacturing process thereof

A process for producing a shooting color-changing target paper, wherein comprising the following steps:

• S1:
• prepare a substrate as follows:
• dye a paper into a dyed paper with a striking-color for subsequent use;
• S2:
• attach a BOPP optical film as follows:
• adhere the BOPP optical film on the dyed paper with an adhesive;
• S3:
• place the BOPP optical film adhered to the substrate on a printing device as follows:
• wind two ends of the substrate with the BOPP optical film prepared in step S2 on a winding assembly of the printing device, such that the BOPP optical film adhered to the substrate is located on a lower side of a printing assembly of the printing device;
• S4:
• print a target paper pattern as follows:
• start the printing assembly and the winding assembly of the printing device, such that the BOPP optical film adhered to the substrate moves from an unwinding end to a winding end of the winding assembly;
• set a printing pattern of a UV-printing ink layer according to design and use requirements;
• and print the UV-printing ink layer by the printing assembly using a UV special-purpose ink on the BOPP optical film;
• S5:
• cure with a UV lamp as follows:
• turn on the UV lamp, which is part of the printing device;
• dry and cure the target paper pattern by the UV lamp to form a finished product of a printed target paper;
• and wind up the finished product of the printed target paper by a winding section of the winding assembly to form a roll of the printed target paper;
• and
• S6:
• package the finished product as follows:
• cut the roll of the printed target paper roll cured in step S5 into a desired size and shape, and then package and warehouse the same.
