Agriculture & Animal Nutrition

First, confirm whether the line runs continuously or pauses in each packaging cycle, and identify what you are coding: woven feed bags, pet food pouches, plastic drums, labels or cartons. Then narrow down TTO models: D06S supports both continuous and intermittent modes, making it the most versatile. For continuous production without stops, prefer D06S in continuous mode. For lines that pause between cycles, compare D118i at up to 120 prints/min, D158i at up to 300 prints/min and D06S at up to 350 prints/min. Laser coding is not excluded by continuous or intermittent operation. Match the machine to the line: D118i suits medium- and low-speed feed bag label and packaging film lines up to 120 prints/min with no air supply needed; D158i suits high-speed intermittent lines up to 300 prints/min; D06S suits high-cadence continuous or intermittent flexible packaging lines and supports 32 mm and 53 mm printheads. Laser figures of 8,000 mm/s and 12,000 mm/s are galvanometer scan speeds, not line speeds, so confirm with stable line speed, code size, content volume and real packaging samples.

Agriculture and pet food lines also require verification of adhesion on woven bag surfaces, mark durability outdoors and in humid conditions, and code readability in dusty environments.

When selecting by coding content, first rule out unsuitable options. Calculate the maximum outline of the content and exclude TTO models accordingly: D118i prints 24/32 mm×15 mm and D158i prints 32 mm×15 mm, so any content exceeding those ranges eliminates that model; D06S prints 32/53 mm×75 mm in intermittent mode or 32/53 mm×150 mm in continuous mode, the largest coverage among TTO printers. If content exceeds 53 mm×150 mm, exclude single-head TTO and select a laser by field lens range. Then define precision and color requirements: for fine, high-density QR codes, avoid 200 dpi D118i as first choice and prefer 300 dpi D158i or D06S or the matching laser, confirming with minimum module size and verification grade samples. For specified color graphics, do not assume lasers produce the target color by default; confirm colored TTO ribbons for color number and adhesion, or validate laser color on real materials.

Second, match technology by content type. Variable data such as production date, batch, serial number, traceability codes, counters and plain text can be compared across all technologies, with material, speed and cost deciding. For high-density small codes, fine characters and low-heat content, prefer UV laser.

In general, plain variable text has the widest application, but no technology covers everything. QR codes, logos, multi-language text and long text must meet size, resolution and readability together. Permanent and anti-counterfeiting marks must pass field tests on real materials. Content fit is only an initial filter and must be combined with other factors.
