With the increasing demand for short-run printing, variable data printing, and personalized printing, digital printing has developed rapidly, and various digital printing devices of various models and functions have appeared on the market. Then, in the face of the digital printing equipment, how should traditional printing companies choose? We analyze for you, the specific issues you should consider when selecting equipment.
At present, according to the printing principle of digital printing equipment, the existing digital printing equipment on the domestic market can be classified into DI type, electrostatic image type, ink jet type, and magnetic recording type.
In the actual production of color separation, electrostatic imaging digital printing equipment is the most widely used, the most flexible form, so we focus on how to choose electrostatic imaging digital printing equipment.
1. Comprehensive consideration of equipment performance parameters
The performance parameters of digital printing equipment mainly include printing speed, resolution, paper feeding method, color number, printing format and color consistency. When purchasing digital printing equipment, traditional printing companies can not simply consider a certain parameter, and do not excessively pursue the perfection of parameters, as long as it is suitable for the development of their own enterprises.
In terms of printing speed, the printing speed of digital printing equipment is related to various factors such as ink coverage, paper size, thickness of printing materials, single-sided printing or double-sided printing, color number and the like. Most digital printing equipment suppliers are priced at 8.5" x 11" on a single-sided printing when printing speed is mentioned. When double-sided printing is performed, the speed is lower than the nominal. When printing in five or six colors, the speed will be slower than four-color printing. In addition to other packaging, the thickness of the substrate will also affect the actual printing speed. Some digital printing devices maintain the same speed regardless of which material is printed, but more digital printing equipment will slow down when printing thicker substrates. When printing linen or synthetic paper, the printing speed will also be Slow down. For the current digital printing equipment on the market, CTF, professional-grade digital printing equipment can generally print at speeds of up to 5,000 sheets per hour (A4).
In terms of resolution, traditional printing companies should pay attention to their actual output when purchasing digital printing equipment. Resolution includes both cross-track and in-track data. If the resolution of a digital printing device is 1200 dpi x 1200 dpi, the cross-track and in-track resolutions are the same. If only one resolution data is available on the promotional material, you should ask for detailed data on the resolution. If the digital printing equipment produced by a digital printing equipment supplier has a real resolution of 1200 dpi x 600 dpi X-Rite, it may claim that its digital printing equipment has a resolution of up to 1200 dpi. In addition, even if the resolution of the digital printing device is the same, it is not always possible to print the same quality of the print, because the size of the dots will be different. Digital printing equipment with small dot size and slightly lower resolution may print images with higher quality than digital printing equipment with higher resolution but larger dot size.
In terms of paper feeding methods, traditional printing companies should select digital printing equipment according to the amount of printed matter. If you have a larger print size, you can choose a continuous paper type; if you have a lot of short work, you can choose a single paper type. In addition, if the papers of the traditional printing companies are relatively fixed, you can choose a single-sheet digital printing device; if the printing volume is relatively large and the paper used is relatively simple (such as books or transaction bills), you can consider continuous Paper type digital printing equipment.
Printing and packaging cities in terms of color number, printing companies should choose according to the type of their customers. For printing companies that serve the high-end market, color numbers may seem important, with multi-color digital printing equipment available, but for general commercial printing companies, four-color digital printing equipment is sufficient.
In terms of printing format, Esko, the printing format of digital printing equipment is closely related to the business that can be undertaken. If the digital printing equipment to be purchased is to print a variety of products of different specifications, such as calendars, menus, etc., the printing company must carefully examine the printing format of various digital printing equipment, because it is closely related to what kind of jobs can be printed. . However, printing companies should pay attention to the large electronic supervision code on the printing scale, which means that the service cost is relatively high.
In terms of color consistency, today's digital printing devices basically guarantee color consistency. However, due to the age of the parts and the use environment have an impact on the quality of the printed image, some digital printing equipment suppliers also provide other means to maintain color consistency, such as Xeikon8000 with two online density meters; Kodak NexPress with There is IntelligentCalibrationSystem (Intelligent Calibration System).
In addition to considering the above performance, it should also consider whether it has an automatic correction function, whether the digital printing equipment is practical and stable.
2. Better compatibility with substrates
Digital printing equipment is a professional-grade fine output equipment. The requirements for substrates are particularly strict. The thickness of the printing materials will affect the printing company's use of digital printing presses. If the printing company serves a specific market, the printing materials may be relatively fixed, and the change is not a large printing market. However, for commercial printing, it is very important to have a wide range of printing materials.
Therefore, when printing digital printing equipment, printing companies should consider their suitability for substrates. If digital printing equipment is not compatible with packaging anti-counterfeiting, it will not only seriously affect the printing quality, but also cause different degrees of equipment. Damage, and later maintenance costs will also increase. If the customer needs to print some special printing materials, the printing company should also test it on the digital printing equipment to be purchased.
3. Seamlessly interface with traditional printing processes
When printing companies choose digital printing equipment, they should also consider whether digital printing equipment can be smoothly integrated with their traditional printing processes. Unlike traditional printing equipment, metal packaging, the quality and performance of digital printing equipment depends to a large extent on the function of the printing process software it carries. The same digital printing equipment hardware, with different printing process software, print quality and productivity often vary greatly. If the printing company already has a complete set of printing process software, you should choose a digital printing device that can be seamlessly connected to the original printing process. At the same time, printing companies should also consider whether the digital printing equipment to be purchased supports ICC color management, PDF/X4, variable data printing, and page description languages such as PDF, PPML, and AFP.
In addition to three-dimensional printing, printing companies should also actively communicate with digital printing equipment suppliers to fully understand the comprehensive cost of the introduction of equipment, the ease of operation of the equipment and the perfect after-sales service.
