Problems solved by technology

But it cannot meet the needs of waterproof, high gloss, and durability at the same time, let alone meet the needs of waterproof, high gloss, anti-counterfeiting, and durability at the same time
[0004] At present, the ordinary inkjet printing photo paper produced on the market has many disadvantages. Most of the products are not waterproof and are easily discolored by humidity in the air; The final image lacks three-dimensionality, which affects the aesthetic effect
In addition, the existing digital high-gloss waterproof photo paper is coated in two steps when using extrusion coating technology. One-way drying is a semi-finished product. This process affects work efficiency because it cannot be coated at one time.
[0005] Moreover, the existing domestic RC photo paper process is to use PE coating on both the front and back of the base paper in the composite process, so that the paper produced in this way has low gloss, soft paper, low stiffness, and is not completely waterproof. Features

Abstract

The invention relates to an RC microporous composite digital photo paper and its production process. The RC microporous composite digital photo paper includes the following four layers: RC photo paper base layer, PET film layer, OPP matt film layer and polymer coating layer. Its production process includes a lamination process and a coating process. In the lamination process, a dry lamination machine is used to cover the back of the RC paper base with PP, and the front is covered with PET, and then the wave flow extrusion coating machine is used to coat the PET film. The surface is coated with polymer. The beneficial effects of the present invention are as follows: the RC photographic paper prepared by the present invention has fine and smooth surface, can improve the surface gloss of photographic paper, play a high-gloss effect when forming an image, and meet the requirements of three-dimensional beauty; it can have a strong Waterproof function, no deformation or wrinkle after soaking in water, no discoloration after soaking in water for 48 hours; one-time coating can be achieved by squeezing the coating head, which can improve work efficiency; it has high gloss, high ink absorption, and 100% waterproof , good stiffness.

Description

technical field [0001] The invention belongs to the field of digital photo paper, and in particular relates to an RC microporous composite digital photo paper and a production process thereof. Background technique [0002] With the rapid development of electronic information technology, the technology of digital products has made a breakthrough. More and more traditional photo output adopts digital printing technology, that is, digital camera is used to take pictures, and then the digital camera is connected to the computer with a data cable. A computer drives a color inkjet printer to print images on digital inkjet photo paper. This kind of digital inkjet printing photo paper is becoming more and more common. It mainly includes high-gloss color reproduction layer, ink-absorbing coating, primer layer and RC photo paper base. The primer layer is between ink-absorbing coating and RC photo paper. Between the bases, the RC photo paper base is composed of a double-sided base pho...
