Smooth and transparent plastic box's relationship with color effect

1, plastic box smoothness and color effect.

Transparent plastic box smoothness is the technique evaluation index plastic box surface uneven degree, is therepresentation of a physical quantity box surface smooth, smooth and uniform degree of vacuum, in certain conditions, so that a certain volume of air, the plastic box test sample surface under certain pressure and flowbetween the smooth glass surface the time required to measure, the expressed in seconds. The number of secondsthe higher smoothness and better glue box. The glue box smoothness and better, the contact surface and a printing plate between materials printing, but also more uniform and complete, the layout (letterpress) or blanket layer of inktransfer more fully, the printing color effect is better. On the contrary, plastic boxes of raw materials of poor smoothness, ink transfer uneven, inadequate, and raw material surface infiltration on the amount of ink is strong,color is bad, often makes printing inks, hair, hair light. So, printing fine products, wire finer dot diameter, smaller, moreshould use the glue box material printing smoothness good, so that the original good reproducibility.

2, plastic boxes, gloss and color effect.

The glue box gloss transparent plastic box refers to the degree of specular reflection of the surface of the plastic box,expressed as a percentage. The glue box higher gloss, the surface of the mirror like reflection of light, more can show the appearance of bright. In fact, plastic box surfaces except the specular reflection, there are diffuse reflection, the glue box gloss decreased. The glue box of raw materials of high gloss, printing inks, also more vivid, visual effects orink. Can say, plastic boxes of raw materials more smooth, the glossiness is high, the printing color gloss is also higher. The glue box material gloss and smoothness are closely related, but the gloss is not smooth, plastic boxes of raw materials shiny surfaces, the surface is not smooth. From the gloss characteristics of transparent plastic boxes of raw materials, according to the print feature selection box suitable material for printing, is very practical significance.Like the page in the main text books and writing, are advised to use gloss general paper, in order to avoid reflection,make the eyes look a long time will not generate fatigue. While printing to chart based layout, appropriate choosesthe gloss of high PVC, PET, PP material, so that the printing ink evenly, thick, bright eye.
