Today we are going to introduce the packaging container that everyone is familiar with – color box.
Take paper color boxes as an example. Color boxes are mostly semi-rigid packaging in daily life. As the name suggests, it is a packaging method that is neither very hard nor very soft, and has a certain ability to resist stamping, such as corrugated boxes, coated boxes, finely framed gift boxes, etc.
The core difference between the production process of color boxes and soft packages lies in the different printing media. Soft packages use plate rollers while color boxes use CTP plates.

CTP (Computer to plate) is the current mainstream color box plate making method, which is computer plate making, referred to as CTP. It was first developed from photographic direct plate making. It uses software-controlled laser scanning imaging to directly hit the laser beam onto the printing plate. The parts with graphics and text will be photosensitive and retained. After being transparently displayed by the developing machine, the printing will be washed away. The patterned part, the image information is restored on the printing plate and can be used for printing.

The following is a set of color box printing process
STEP 1 Finalize the packaging layout design.


STEP 2 The color box factory accepts the design documents and standardizes the documents. Confirm the spot color, process, box type and size, etc.


STEP 3 Make CTP version. The price of single-color veneer A1 size ranges from tens to hundreds of yuan (this price is derived from the experience of cooperation with some color box manufacturers and is for reference only and is not unique). After publishing, imposition, and printing, it is divided into different color versions CTP according to color.


STEP 4 Proofing. Because the CTP process does not use offset printing, the traditional film proofing method cannot be used. Therefore, the printing factory will choose to use a digital printer to simulate printing colors and print digital samples, and then send the digital samples back to the designer for review. If the product accuracy requirements are relatively high, digital samples will not be used as a reference, but the designer will go directly to the machine to sign the samples during actual production.


STEP 5 Surface processing. After printing, processes are applied as required, such as glazing, lamination, hot stamping, UV, embossing or embossing, etc. Especially gift box products have higher requirements for packaging processes. The designer needs to include the actual process when making the manuscript. The effect is considered in the design, and we will also talk about the effects of different packaging processes in detail later.


STEP6 Die cutting and creasing. Cut according to the corresponding box shape and make creases. Common carton box types include: socket boxes, sky and ground cover boxes, aircraft boxes, bottom lock boxes, roof boxes, etc.


STEP7 Folding boxes and pasting boxes. Fold and paste on the box making machine, and a complete color box is completed.

Regardless of whether it is a hard package or a soft package, the fundamental basis for the packaging production effect is the design documents provided by the demander. In order to ensure that the actual product is as close as possible to the expected effect, the demander must have a realistic prediction of the manuscript. For designers, what should we pay attention to in the production and processing of manuscripts? So next time we will talk about what elements designers need to determine before delivering packaging design manuscripts to the printing factory, so that they can better Control final production results.
