Embodiment 1

[0012] Embodiment 1: the grating covered on the surface of a 20.1-inch liquid crystal display screen with a dot pitch of 0.255m / m, the transparent gap is 0.09m / m, and the grating is made of transparent plastic material, such as PVC or other polyester transparent objects. At this time, the part through the grating is one-third of the display screen, and the display screen is displaced. The distance of each displacement is exactly one-third of the dot pitch of the display screen. After the display screen has been displaced three times vertically and three times horizontally , the pixels of the LCD screen are enlarged by 9 times. At this time, the photo paper is exposed step by step. The exposure time is 0.2-10 seconds. The photo paper after exposure is transferred to the color photo paper processing machine for washing. 45 seconds, turn to the bleaching tank to bleach for 45 seconds, then enter the two stabilization tanks in turn, stabilize for 45 seconds respectively, and finall...

Embodiment 2

[0013] Embodiment 2: The surface of a liquid crystal display screen with a 19-inch dot pitch of 0.294m / m is covered with a grating gap of 0.1m / m, and one-third of the display screen passes through the gap of the grating. After moving vertically and horizontally several times in the horizontal plane, the pixels of the liquid crystal display screen have also been enlarged several times, and after step-by-step exposure, repeat the developing process of Embodiment 1 to obtain high-definition photos.

Abstract

This invention relates to a color photo development method, which comprises the following steps: a to feed the printing paper to the feeding platform; b to absorb photographic printing paper on the feeding platform to apron band; c to expose in steps, wherein, the LCD or feeding platform moves all-round direction and exposes in steps, the exposure time is 0.2 to 10 seconds; d the photographic paper enters the development machine for development. This invention adopts exposure in steps and covers a transparent grating on the surface of the LCD, and uses grating dell displacement step light sensation, which improves the light sensitive picture elements with nine times and solves the clearance of the digital photos.

Description

Technical field: [0001] The invention relates to the technical field of photo printing, in particular to a color photo printing method. Background technique: [0002] At present, the existing digital image printing, in addition to laser scanning, is generally realized through the liquid crystal chip image projection, magnification and imaging. However, the photosensitive pixels are often low, and the printed photos are not enough in clarity, color, and gloss. Ideal, incomparable to traditional film-sensitive color photos. Invention content: [0003] The purpose of the present invention is to provide an improved color photo printing method, which can overcome the shortcomings of low photosensitive pixels and insufficient clarity of photocopying in the prior art. [0004] In order to achieve the above object, the technical solution of the present invention is: a color photo printing method, characterized in that: the color photo printing method includes the following steps:...
