In brief
Start with the substrate, artwork, process window and finished-part acceptance criteria; then select sheet-fed or roll-to-roll automation and the options needed to control them.
Start with the material and feed format
A machine choice begins with what enters and leaves the line. Record whether the job uses precut sheets or a continuous web, the material family, thickness range, surface condition, roll diameter, liner construction and final delivery format. A roll-to-roll line can reduce handling for stable long runs, while sheet automation can suit precut parts, frequent artwork changes and jobs that need individual CCD alignment. The same artwork should be trialled on the actual production material because curl, static, shrinkage and surface energy can change registration and ink transfer.
Define registration as a finished-part requirement
Do not compare only a camera or table positioning number. Define the mark design, number of colours or functional layers, distance between critical features, measurement method, sample locations and allowed error after drying. Web tension, material shrinkage, screen stability and the cure path all contribute to final registration. LICHAO's LC-6080SYJ-C page publishes a CCD repeat-registration figure of ±0.03 mm, while the final part still requires a representative sample trial and agreed inspection method.
Match ink deposit and curing to the process
Industrial screen printing may deposit graphics, conductive ink, dielectric, adhesive or other functional layers. State the smallest feature, target dry-film thickness, ink supplier, mesh and stencil constraints, number of passes and cure window. For a web line, include dryer path, temperature zones and rewind condition. For a sheet line, include loading, alignment, unloading and any downstream cure or inspection station. A machine that can move the substrate is not automatically qualified for the ink stack.
Calculate useful output instead of headline speed
Useful output is accepted parts per shift. Include loading or unwind time, alignment, print stroke, flash or full cure, screen cleaning, colour changes, inspection, splices, roll changes and scrap. Ask the supplier to state which operations are included in a quoted cycle rate. A slower nominal speed with stable registration and lower scrap can produce more accepted parts than a faster line with frequent intervention.
Specify the required automation boundary
List each operation that must be automatic: unwinding, liner peeling, static removal, dust cleaning, web guiding, mark tracking, printing, drying, inspection, laminating, rewinding, sheet feeding or unloading. Do not purchase an undefined 'fully automatic' label. The LC-FZSYJFG-6060 page, for example, identifies dual unwind, liner peeling, dust removal, CCD alignment, vacuum tension boxes and two-side laminating rewind as separate functions.
Use a sample acceptance plan before the quotation is final
Send controlled artwork, representative material, the ink or coating data sheet, target output and measurable acceptance criteria. Record registration, deposit, adhesion, cure, visual defects, electrical performance when applicable and results across the run—not only the first sample. The quotation should identify the tested configuration, utilities, floor space, training scope and any options that remain conditional.
