How to Choose Pad Printing for Plastic Parts: US Buyers

Choose a pad-printing supplier by confirming order eligibility and technical fit before shipping parts, then agreeing on sample approval, pricing and production-lot acceptance. Separate the supplier’s stated requirements from the terms you need to negotiate.

Check order eligibility before requesting prices

Start with these screening questions:

• Will you accept customer-supplied plastic parts for this job?
• Will you accept the quantity and order frequency—one-time, occasional or recurring?
• Can you serve the delivery destination, and what production unit counts toward your minimum?

Pad Printing Services Inc. requires more than 5,000 identical prints per order, repeated every month, and says it is not accepting one-time orders. Exactly 5,000 does not satisfy that wording. Its price examples for up to 500 units do not establish eligibility for a small or one-time job. [2]

Ask whether “prints” means printed parts, individual impressions or another production unit, especially when each part needs graphics in multiple locations.

Serviscreen’s Michigan contract-printing operation offers long and short runs. [3] Its FAQ says it has no minimum order quantities, noting that setup makes first-piece costs much higher than incremental costs. [4] Request confirmation of your actual quantity, schedule, supplied parts and delivery destination before proceeding.

Screen resin, geometry, print area and color count

Send a technical screening packet before shipping parts: resin designation, available material documentation, overall dimensions, surface description, print dimensions, number of print locations and color count. Request approval of the exact configuration—not confirmation that the supplier “prints plastic.”

American Plastic Products lists ABS, PVC and polyethylene, along with flat, curved, uneven, textured, recessed and multiple-location applications. Its stated limits are a 3 × 3 × 6-inch object and one or two colors. [1] APP identifies polypropylene and acetal as materials that may require pretreatment for ink adhesion; this is provider-specific guidance. [1]

Object size is not printable image area. APP and Pad Printing Services Inc. do not state numeric maximum print areas. [1][2] Request a marked-up approval showing the accepted graphic footprint at each location.

Pad Printing Services Inc. lists ABS, PVC and PC as its routine plastics and excludes completely assembled electronic products and tubes or bottles containing product. [2] Its separate discussion of polypropylene and nylon says Corona Plasma pretreatment adds cost and may leave wet marks on some polypropylene brands, making samples necessary. [2] Obtain written clarification before treating either resin as accepted under its narrower material policy.

Prepare artwork, a location drawing and a color reference

Pad Printing Services Inc. specifies the following intake package: [2]

• Required artwork: outlined vector artwork inside a PDF.
• Required placement information: a CAD or similar drawing showing print location.
• Required color reference: a Pantone/PMS number.

A PDF filename is not enough: the company rejects a JPG merely saved inside a PDF, as well as AI, EPS, JPG and bitmap submissions. [2]

As buyer preparation—not universal supplier requirements—make the location drawing identify print dimensions, orientation, reference features for measuring placement and every print location tied to its artwork. Use a shared revision identifier across the artwork, drawing and color reference, and ask the supplier to reference it when returning proofs.

If files need work, APP lists artwork adaptation and print-placement support among its services. [1] Confirm the scope and charges. Keep the PMS target separate from acceptance: agree on how production color will be assessed rather than treating a color number as the complete standard.

Agree on sample parts, ink trials and fixtures

Pad Printing Services Inc. asks for three sample parts, which it does not return, to test ink and fixturing before it sets print pricing. [2] With other suppliers, agree on how many representative parts to provide and what the supplier may consume during trials.

Put trial costs, pretreatment experiments, responsibility for damaged samples, and return or disposal arrangements in writing. Ask the supplier to document the proposed ink, pretreatment and curing approach against the intended end-use exposures.

Clarify the printing passes required. Pad Printing Services Inc.’s “single-hit” assumption is dark ink on light, non-textured, non-glare plastic; light ink on a dark surface usually requires two hits and sample printing before pricing can be set. [2] Request a proposed approach for the actual resin, surface and graphic.

Separate fixture charges from fixture rights. Pad Printing Services Inc. lists no separate charge for fixtures, printing plates or art film under its baseline pricing. [2] Do not treat this as an ownership agreement. Ask:

• Who owns the fixture, and can it be transferred to you or another printer?
• How will it be identified and stored between orders?
• Who handles maintenance and pays for replacement?
• Will reuse on repeat orders carry a charge?

Keep permission to conduct trials separate from sample approval and authorization to begin production.

Request itemized pricing, not an extrapolated estimate

Pad Printing Services Inc. labels its figures as rough estimates, with each example applying to up to 500 units: [2]

• Two colors: $145 setup plus $1.25 per unit for up to 500 units. [2]
• Three colors: an estimated $175 setup plus $1.50 per unit for up to 500 units. [2]
• Four colors: an estimated $225 setup plus $2.00 per unit for up to 500 units. [2]

These examples do not override its more-than-5,000-identical-prints monthly requirement or establish the price of an eligible recurring order. [2] Request job-specific pricing rather than extrapolating a production total.

Unpacking and repacking labor is excluded; it requests a packaging description and warns this handling can take as long as printing. [2]

Ask for an itemized quote with each line marked included, separately charged or not applicable:

• Machine setup, fixtures and tooling, including repeat-order charges.
• Artwork changes, sample printing and ink trials.
• Unit printing and pretreatment.
• Unpacking/repacking labor, packaging materials and shipping.

Have the quote identify assumptions about ink hits, print locations, colors, quantities and packaging. Keep trial authorization separate from the production quote.

Approve a reference sample with measurable criteria

Request a written sample-approval record rather than an email saying the print “looks good.” Propose these terms for agreement:

• Approved configuration: part number and resin, artwork revision, location drawing, color reference, pretreatment and a uniquely identified approved sample.
• Acceptance criteria: placement and color-to-color registration limits, color assessment, acceptable cosmetic defects, and an adhesion-test method with pass/fail criteria appropriate to the intended use.
• Approval controls: authorized approver, approval deadline, reference-sample retention and changes requiring another trial.

Ask APP and Pad Printing Services Inc. to confirm numeric acceptance tolerances, adhesion-test methods and sample-signoff procedures. [1][2] Obtain agreement rather than assuming a default standard.

APP’s consistency claims and Serviscreen’s adhesion and durability claims are vendor-reported, not independent lot-level results. [1][3] Use them as prompts for qualification, not substitutes for an approved sample and acceptance criteria.

Keep graphic approval separate from production release: request a distinct written authorization before the full lot is printed.

Put lot acceptance and remedies in writing

Turn the approved sample into a production-lot agreement. The following are proposed terms to negotiate, not established contractual rights:

• Lot acceptance: identify the reference sample and revision, inspection method, defect categories, inspection quantity or sampling approach, and lot pass/fail decision.
• Inspection and notification: name who inspects at the supplier and on receipt; agree on discrepancy records and reporting deadlines.
• Rejected or damaged parts: assign responsibility for supplied components, authority to rework or dispose of rejects, available replacement, reprint or credit remedies, and return freight.
• Recurring-order changes: specify which changes to resin, part revision, artwork, ink, treatment or fixtures require notification, renewed qualification and approval.
• Commercial terms: agree on lead time, shipping responsibility, cancellation, refunds and warranty coverage.

Resolve disagreements before releasing production, and attach the approved terms to the order.

What to confirm with each provider

The cited pages leave these job-specific details unresolved:

• American Plastic Products: price, numeric minimum, service area, sample requirements, fixture rights and lot-rejection remedies. [1]
• Pad Printing Services Inc.: eligible recurring-order pricing, handling rate, pretreatment surcharge, turnaround, fixture rights and lot-rejection remedies. [2]
• Serviscreen: price, sample and fixture requirements, packaging terms and lot-acceptance criteria. [3]

Send one qualification request before shipping

Include quantity and order frequency; resin, dimensions and intended use; artwork, print size, locations and color reference; and unpacking/repacking details and delivery destination.

Request written confirmation of eligibility and technical acceptance, sample quantity and trial costs, itemized production pricing, and sample-approval and lot-acceptance terms.

Confirm eligibility first, authorize sample work second, then obtain final pricing and approve the sample. Release production after acceptance terms are agreed, with sample consumption and return arrangements resolved before valuable parts are shipped.
