Question 1

What is serialization in pharma and tobacco track-and-trace?

Accepted Answer

Serialization in pharma and tobacco track-and-trace means each saleable unit and case carries a unique, government-registered code tied to a national database, so it can be verified as authentic and tracked through the supply chain. SHICAI coders print these serials at speed from MES/ERP, meeting the mandates that now cover those industries. Unique, database-backed codes are what let an inspector confirm a pack is genuine in seconds. Choosing between inkjet, laser and thermal transfer comes down to substrate, speed, permanence and whether you want zero consumables (laser) or flexible, low-cost marks (inkjet). Coding and marking equipment is used across food and beverage, pharmaceutical, cosmetics, cable, electronics and building materials for dates, batches and traceability. Across industries the pattern is the...

Question 2

How does coding help anti-counterfeiting and brand protection?

Accepted Answer

Coding helps anti-counterfeiting by putting a unique, recorded mark on products that fakes cannot easily clone in bulk, and by letting customers or inspectors verify authenticity via a scanned code. SHICAI variable-data and serialized printing turns the code into a brand-protection tool, not just a logistics label. Combined with a verification app or database, the code becomes a trust signal at the point of sale. Coding and marking equipment is used across food and beverage, pharmaceutical, cosmetics, cable, electronics and building materials for dates, batches and traceability. Batch and serial codes are the backbone of recall management and brand protection; serialization is now mandated in pharma and tobacco track-and-trace. Inkjet wins on flexibility and cost; laser wins on permanence and...

Question 3

What is the difference between inkjet, laser and thermal transfer marking?

Accepted Answer

Inkjet (TIJ/CIJ/PIJ) lays fast-dry or pigment ink for flexible, low-cost marks on many substrates; laser ablates the surface for permanent, consumable-free coding; thermal transfer (TTO) uses a ribbon for crisp, flat marks on film and labels. Choose inkjet for flexibility and cost, laser for permanence and zero consumables, TTO for static high-res film labels. Many lines mix two: laser or inkjet on primary packs, TTO or label on secondary. Batch and serial codes are the backbone of recall management and brand protection; serialization is now mandated in pharma and tobacco track-and-trace. The global coding and marking market keeps growing as regulators and retailers push 2D barcodes and supply-chain transparency. Inkjet wins on flexibility and cost; laser wins on permanence and...

Question 4

What print height do I need for my codes?

Accepted Answer

Choose print height by the largest mark you need: date/text on cartons is fine at a few mm, while large case or pallet codes need more. SHICAI handheld and desktop cover 2-12.7 mm; larger character work uses PIJ or DOD heads. Size up a little for readability at distance. Too small a height and codes become unreadable; too large wastes ink and head cost. Plan for GS1 Digital Link and 2D barcodes (retail mandates arriving 2027) so the line is not obsolete in two years. Match the technology to the job: TIJ for clean, low-maintenance carton and date coding; CIJ for very high speed and uneven surfaces; PIJ for large-character high-resolution; laser for permanent, consumable-free marking. Future-proofing is now concrete:...

Question 5

How do I future-proof for GS1 Digital Link / 2D barcodes (2027)?

Accepted Answer

Future-proof by choosing a coder that already prints GS1-compliant 2D barcodes (QR/DataMatrix) at 600 DPI with quiet zone, because retailers&#8217; 2D-barcode mandates arrive through 2027. A machine bought today should speak GS1 Digital Link so you are not replacing it when the mandate hits. SHICAI inline and egg coders are built around 600 DPI 2D output for exactly this shift. Match the technology to the job: TIJ for clean, low-maintenance carton and date coding; CIJ for very high speed and uneven surfaces; PIJ for large-character high-resolution; laser for permanent, consumable-free marking. For scannable QR and barcodes plan at least 300-600 DPI and enough quiet zone; higher line speeds need faster printheads or multiple heads. Future-proofing is now concrete: retailers&#8217; 2027...

Question 6

Handheld, desktop or inline &#8211; which form factor fits?

Accepted Answer

Pick the form factor by volume and location: handheld for portable, intermittent marks; desktop for bench, low-volume consistent coding; inline for high-speed, continuous line printing. The decision is mostly about how many items per hour and whether the item comes to a fixed station or moves on a belt. Many operations use two form factors &#8211; handheld for exceptions, inline for the main flow. For scannable QR and barcodes plan at least 300-600 DPI and enough quiet zone; higher line speeds need faster printheads or multiple heads. Ink must suit the substrate &#8211; fast-dry for non-porous plastic/metal, food-grade for eggs and pharma, pigment for colored or recycled surfaces. The single most common mistake is buying on price per machine and...

Question 7

What questions should I ask a manufacturer before buying?

Accepted Answer

Before buying, ask: what is the real max speed at my print height; which ink fits my substrate; are CE/ISO and low-migration inks available; does it integrate with my MES/ERP; what are spare-part lead times; and can I get a print sample? A manufacturer that answers concretely &#8211; like SHICAI&#8217;s Ganzhou engineering team &#8211; is one you can trust post-sale. A print sample on your actual material is the single best de-risking step. Ink must suit the substrate &#8211; fast-dry for non-porous plastic/metal, food-grade for eggs and pharma, pigment for colored or recycled surfaces. Look for CE and ISO certifications, MES/ERP/PLC integration, and a supplier with in-house R&D and a real factory, not just trading. The single most common mistake...

Question 8

What is the difference between DOD and TIJ printing?

Accepted Answer

DOD (drop-on-demand) and TIJ are both inkjet, but TIJ uses pre-packaged thermal heads/cartridges (simple, low-maintenance, great for cartons/dates), while DOD uses valve or piezo jets for larger characters and rougher surfaces. For most carton and date coding, TIJ is cleaner; for big, outdoor or porous marks, DOD/PIJ fits. SHICAI&#8217;s TIJ handheld/desktop and PIJ large-character lines map to these two needs. Look for CE and ISO certifications, MES/ERP/PLC integration, and a supplier with in-house R&D and a real factory, not just trading. Plan for GS1 Digital Link and 2D barcodes (retail mandates arriving 2027) so the line is not obsolete in two years. A supplier with its own factory and R&D (SHICAI runs both in Ganzhou) can support customization and spare...

Question 9

How do humidity and dust affect industrial printers?

Accepted Answer

High humidity can slow ink drying and affect charge-based CIJ deflection; dust and debris can clog nozzles or lenses. SHICAI coders are built for industrial environments, but site them with reasonable airflow, keep the printhead covered when idle, and follow the simple cleaning routine to stay reliable. For washdown or very dusty areas, an IP65-rated or enclosed head is worth specifying. Plan for GS1 Digital Link and 2D barcodes (retail mandates arriving 2027) so the line is not obsolete in two years. Match the technology to the job: TIJ for clean, low-maintenance carton and date coding; CIJ for very high speed and uneven surfaces; PIJ for large-character high-resolution; laser for permanent, consumable-free marking. A supplier with its own factory and...

Question 10

How do I choose between TIJ, CIJ, PIJ and laser?

Accepted Answer

Match the technology to the job: TIJ for clean, low-maintenance carton and date coding; CIJ for very high speed and uneven or recessed surfaces; PIJ for large-character, high-resolution marks; laser for permanent, consumable-free coding. The right pick follows your substrate, line speed and whether you need zero running cost. Most buyers shortlist two of these; a supplier with all four (like SHICAI) can advise without a bias toward one machine. Plan for GS1 Digital Link and 2D barcodes (retail mandates arriving 2027) so the line is not obsolete in two years. Match the technology to the job: TIJ for clean, low-maintenance carton and date coding; CIJ for very high speed and uneven surfaces; PIJ for large-character high-resolution; laser for permanent,...

Question 11

What is an IP65 rating and do I need it for washdown areas?

Accepted Answer

IP65 means the enclosure resists dust ingress and low-pressure water jets &#8211; suited to washdown areas in food and beverage plants. If your coder is hosed down or exposed to spray, specify an IP65 (or higher) rated head and cabinet so cleaning does not damage electronics. Pair it with food-grade ink and you meet most hygienic-line coding needs. Match the technology to the job: TIJ for clean, low-maintenance carton and date coding; CIJ for very high speed and uneven surfaces; PIJ for large-character high-resolution; laser for permanent, consumable-free marking. For scannable QR and barcodes plan at least 300-600 DPI and enough quiet zone; higher line speeds need faster printheads or multiple heads. Future-proofing is now concrete: retailers&#8217; 2027 2D-barcode mandates...

Question 12

TIJ vs CIJ: which is right for my packaging line?

Accepted Answer

For packaging lines, TIJ wins when the surface is clean and flat (cartons, cases) and you want near-zero maintenance; CIJ wins on very high speed, curved or non-porous bottles, and where a long throw distance helps. TIJ has no solvent loop; CIJ outruns it on the fastest lines. If the line is mixed, some sites run TIJ for cases and CIJ for primary packs. Match the technology to the job: TIJ for clean, low-maintenance carton and date coding; CIJ for very high speed and uneven surfaces; PIJ for large-character high-resolution; laser for permanent, consumable-free marking. For scannable QR and barcodes plan at least 300-600 DPI and enough quiet zone; higher line speeds need faster printheads or multiple heads. The single...
