Handle short-run and multi-SKU orders: It is suitable for short-run, multi-SKU, frequently changing and customized label production. Support variable data printing: It can be used for QR code labels, barcode labels, serial number labels, variable data labels and anti-counterfeit labels. Cover common label applications: Typical applications include food packaging labels, cosmetic labels, daily chemical labels, industrial product labels and brand protection labels. Improve production flexibility: Compared with traditional flexo or letterpress workflows, digital label printing is more suitable for small-batch orders, fast order switching and personalized label production. Roll-to-Roll PET, BOPP, PVC, PP, PE, OPP films and synthetic label materials should be tested before batch production. Some difficult-to-print materials may require corona treatment or other surface treatment to improve UV ink adhesion. Heat-sensitive films require proper UV curing settings and temperature control to reduce deformation or discoloration. QR code labels, barcode labels, serial number labels and anti-counterfeit labels should be tested for readability and data accuracy. White ink and varnish are optional for selected applications, depending on material compatibility and machine configuration. Stable roll-to-roll label printing requires proper tension control, clean workshop conditions, stable power supply and regular printhead maintenance. Corona treatment unit or surface treatment unit for improving UV ink adhesion on selected label materials Material Cleaning Unit Removes dust from the material surface Ensures printing quality Fully Automatic Plate-making System Although digital printing does not require plate-making, some factories still retain this system Used in coordination with traditional printing equipment

Comparative Positioning

Side-by-side benchmarks against peer manufacturers in this segment.

Compared To Difference Performance Gap Best For Cost Difference Efficiency
Traditional flexo label printing / Letterpress label printing GR350S uses roll-to-roll UV inkjet digital printing without traditional plate-making. It is more suitable for short-run, multi-SKU, variable-data and customized label orders, while traditional flexo or letterpress printing is more suitable for long-run and stable label jobs. The cost and efficiency difference depends on order quantity, label size, material type and job change frequency. Digital label printing can reduce plate-making steps and setup time for small-batch and frequently changing orders, while traditional flexo printing may still have cost advantages for very large-volume repeated orders. GR350S is suitable for short-run labels, multi-SKU packaging labels, QR code labels, barcode labels, serial number labels, anti-counterfeit labels, cosmetic labels, food packaging labels, daily chemical labels and customized small-batch label orders. GR350S can reduce plate-making cost and setup waste for small-batch and variable-data label orders. Traditional flexo or letterpress printing may be more economical for long-run repeated orders with stable artwork and large quantities. Higher overall efficiency for mixed jobs: processing multiple SKUs in one continuous run Lower energy consumption per label for short-run jobs (eliminating long pre-press and setup cycles) Consistent print speed across different designs, unlike traditional processes that require adjustments for new plates
