RC micro-porous composite digital photopaper and production technology thereof

Abstract

The invention relates to RC micro-porous composite digital photopaper and a production technology thereof. The RC micro-porous composite digital photopaper comprises the following four layers: an RC photopaper base layer, a PET film layer, an OPP matt film layer and a macromolecular coating layer. The production technology comprises composite operation procedures and coating operation procedures, in the composite operation procedures, a dry compositing machine is adopted to coat the back surface of the base layer of the RC photopaper with the PP matt film layer and coat the front surface of the base layer of the RC photopaper with the PET film layer, and macromolecular coating is conducted on the surface of the PET film layer by adopting a wave-current extruding coating machine. The RC photopaper prepared by the production technology disclosed by the invention has the benefits that the surface is fine and smooth, so that the surface gloss of the photopaper can be improved, the RC photopaper has a high light effect during imaging, and requirements for stereoscopy and beautiful appearance can be met; the RC photopaper has a better water-proof function, deformation and wrinkles do not exist after the RC photopaper is immersed in water, and color change does not exist after the RC photopaper is soaked in the water for 48 hours; through extruding a coating head, one-time coating is realized, so that the operating efficiency can be improved; the RC photopaper has the advantages of high glossiness, good ink absorbing property, water-proof property of 100% and 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...

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
