Before starting to print not only to prepare the printing ink that has to be used, but also based on the must, its hue and packaging printing characteristics to carry out the formulation, in order to consider the must of packaging printing. Hardware etching equipment manufacturers with ink before the first to estimate the relative ink consumption, so that the amount of ink adjustment is moderate. Especially for two-liquid reflective printing ink, should be based on its dry solid rate and packaging printing rate to estimate the amount of ink adjustment.
1. hue in the printing ink colour mixing, one should pay attention to the light source on the printing ink colour hazards. Generally should be carried out in the sunlight under the colour, the hue is more. And in the manpower light source under the colour, you need to select the presentation of the better light source, fluorescent lamps presentation of the actual effect of the poorer. Preparation of printing ink, should be selected and the colour of the colour is more close to the tone, and then according to add a small amount of other shades can be obtained the required tone. Multi-colour printing ink should be used to minimize the preparation. Due to the preparation of commonly used printing ink colour saturation, the more intermediate colours, the higher the grey scale, the darker the tone, but also to promote the preparation of printing ink is not easy to grasp. In the actual preparation of ink, should probably be clear about the colour of the colour, selected relative printing ink, and then slowly add auxiliary ink. In the addition of dark brown ink should pay attention to gradually add, do not have to add too little at a time, otherwise it is very easy to lead to consumption, but also prompted the preparation of several times.
2. Packaging printing characteristics of the adjustment in the packaging printing, because the printing process, the natural environment standards, metal mesh and many other factors, many printing inks can not be considered without the preparation of the application regulations, so before the application of the packaging printing characteristics must be carried out moderately before the preparation. Generally, it is mainly based on the addition of neutralising agents to improve its packaging and printing characteristics. Such as metal mesh screen mesh is higher, the drying rate should be on the slow side, then can add a small amount of stop drying agent. And coarse network packaging printing, viscosity should be slightly larger, dry agitation rate should be slightly faster, then should add the appropriate amount of drying agent. Hardware etching equipment manufacturers in the addition of neutralising agent to carry out the preparation, must be stirred evenly, the amount of its use but also to manipulate the right amount, or the actual effect is likely to outweigh the loss.
