Digital printing is an ideal choice for small batches and personalized needs Digital printing technology has become the preferred solution for short form printing due to its characteristics of no need for plate making and fast response. With the technological iteration of digital printing machines such as HP Indigo and Konica Minolta, their quality has approached that of traditional offset printing, making them particularly suitable for meeting personalized and variable data printing needs. The biggest advantage of digital printing lies in zero plate making costs and flexible batch adaptability. Among the printing demand of 1-500 copies, the single cost of digital printing is significantly lower than that of offset printing. Suitable scenarios include personal portfolio, exhibition brochure, customized invitation letter, etc. A certain design studio produces 20 product brochures for clients. Using digital printing not only saves 50% of the cost compared to offset printing, but also prints different client names on the title page of each brochure, achieving a personalized experience of one person per edition. Variable data printing is a unique capability of digital printing. Through database linkage, personalized changes in text and images can be achieved in the same batch of printing, such as exclusive identification numbers for membership cards and class names in textbooks. When a certain educational institution printed 100 training manuals, it used this technology to add student names to the header of each book, which increased participation by 25%. Digital printing is slightly inferior to offset printing in terms of large-scale solid color performance, and is prone to slight dot visibility, making it unsuitable for reproducing art pieces that require high color consistency. The adaptability of paper is also limited, as special materials that are too thick (>300g) neu'n rhy denau (<50g) may cause paper jams or transparency. In addition, digital printing has weak scratch resistance, and it is recommended to apply glue or UV gloss treatment to files that have been stored for a long time. The benchmark technology for large-scale high-quality offset printing Offset Printing, as a representative of traditional printing, is still the mainstream choice in fields such as books, magazines, and packaging due to its high-precision color reproduction and batch cost advantages. The principle is to transfer images and text indirectly from the printing plate to the substrate through a rubber blanket, which is suitable for efficient printing of flat materials. The plate making cost of offset printing determines its suitability for batch printing of over 500 copies. When the printing volume reaches 1000 copies, the single page cost can be reduced to one-third of digital printing. A publishing house printed 5000 novels, and the offset printing solution saved 60% of the cost compared to digital printing, with better color stability. The color management system is the core competitiveness of offset printing. Offset printing machines certified by G7 can control color deviation within Δ E ≤ 1.5, suitable for printing brochures, packaging, etc. that require strict color standards. The product manual of a certain cosmetics brand adopts offset printing+spot color printing technology, which achieves a consistency of 98% for the brand's exclusive colors, far higher than the 90% achieved by digital printing. Offset printing has a wide range of adaptability to paper, from 60g lightweight paper to 350g copperplate paper, all of which can be printed stably. Combined with UV offset printing technology, printing can also be achieved on non absorbent materials such as plastic and metal, such as phone cases and membership cards. The metal bookmark printing project of a certain gift company uses UV offset printing to accurately transfer patterns onto stainless steel surfaces, combining aesthetics and durability. The post-processing compatibility of offset printing is extremely strong, and it can seamlessly integrate with processes such as hot stamping, embossing, and die-cutting. A luxury product packaging adopts a combination of four-color offset printing, hot stamping, and embossing, which increases the high-end feel of the packaging by 40%. This composite process is difficult to achieve with digital printing. Expert in special materials and three-dimensional effects for screen printing Screen Printing uses ink leakage in the hollow areas of the screen template, making it suitable for printing needs of non flat and special materials. Its thick ink layer can create a unique touch and covering power, which is irreplaceable in the fields of industrial printing and customized gifts. Screen printing is almost unrestricted by the substrate and can be printed on surfaces such as glass, wood, fabric, ceramics, etc. The customized mug project of a certain coffee shop uses screen printing to print the brand logo on the curved cup body, which can withstand dishwasher cleaning after high-temperature curing. In T-shirt printing, the ink adhesion of screen printing is more than three times that of digital heat transfer printing, and it is not easy to fade after multiple washes. The thick ink layer effect is the iconic advantage of screen printing. The ink thickness can reach 50-100 μ m, far exceeding the 5-10 μ m of offset printing, suitable for making three-dimensional text, tactile textures, etc. The poster of a certain music festival adopts screen printing and fluorescent ink technology, which not only has obvious raised texture on the text, but also emits fluorescence under ultraviolet light, with significant visual impact. The single plate printing efficiency of screen printing is relatively low, suitable for small batch customization, while large-scale production requires multiple devices in parallel. Although its plate making cost is lower than offset printing, due to slow printing speed, the cost of orders over 500 copies may be higher than offset printing. Efficient solution for flexographic packaging and label printing Flexographic printing has become the mainstream process for packaging printing due to its environmentally friendly and high-speed characteristics. Using flexible photosensitive resin plates, it is suitable for printing packaging materials such as corrugated paper, plastic bags, and stickers, especially widely used in the field of food packaging. Flexographic printing uses water-based ink or UV ink, with VOC emissions only 1/5 of offset printing, which meets the safety standards for food contact materials. The packaging printing of a certain biscuit factory adopts flexographic printing technology and ensures the safety of direct contact between packaging and food through FDA certified ink.
Ar ddeunyddiau nad ydynt yn amsugnol, mae gan argraffu flexograffig adlyniad llawer gwell nag argraffu gwrthbwyso. Mae label potel ddiod benodol yn mabwysiadu'r broses o argraffu flexograffig ac mewn labelu mowld, sy'n integreiddio'r label â chorff y botel ac yn gwella ei wrthwynebiad dŵr a thymheredd yn sylweddol.
