Printing

In industrial case manufacturing, printing is a central means of uniquely identifying products, making information permanently visible, and representing corporate design consistently. At KKC Koffer GmbH, printing covers brand- and function-related labeling of cases, transport containers, foam inlays, and expansion parts up to the branding of complete case systems — from aluminium cases in use and plastic cases to the X-PCK backpack case and the Mobile Work Table in a Case.

Definition: What is meant by printing?

Printing refers to the graphic or functional application of colors, symbols, text, codes, or logos to components and surfaces. In the context of KKC Koffer GmbH, this means permanent, position-accurate, and material-appropriate marking of case exterior and interior surfaces, foams, inlay boards, and panels. The goal is a clear informational benefit — such as identification, allocation, safety notices, or scales — as well as the implementation of branding and corporate design, tailored to material, load, and application.

Processes and technologies for printing

Depending on material, quantity, and requirements, different printing and marking methods are used for cases, transport containers, and fittings. Key methods include:

• Screen printing: high opacity, very good abrasion resistance, ideal for single- to multi-color logos, pictograms, and large-area motifs on flat or slightly curved areas of aluminium and plastic cases.
• Pad printing: for smaller, irregular surfaces and components; suitable for serial numbers, small logos, and labeling of switches and sockets.
• Digital/UV printing: detailed, multi-color motifs up to four-color plus white; advantageous for variable content (e.g., QR, DataMatrix codes) and fine gradients. UV-cured inks offer good chemical and UV resistance.
• Transfer and thermal transfer printing: especially for textile/hybrid surfaces on the X-PCK backpack case; enables flexible, crisp motifs and small quantities.
• Hot stamping/foil stamping: metallic effects, high edge sharpness; suitable for decorative yet robust markings.
• Laser marking (in addition to printing): precise, durable, and solvent-free; suitable for anodized aluminium, coated sheets, rigid plastics, or multi-layer foams with a color layer.

Material-appropriate implementation on cases and expansion parts

The choice of process depends on the base material and the intended load in daily use.

Aluminium cases

On anodized and powder-coated surfaces, screen printing and UV printing offer good adhesion and color density. Laser engraving provides very precise, high-contrast markings, for example for serial numbers, nameplates, or permanent pictograms. For highly stressed areas, a protective coating or overlaminate can be useful.

Plastic cases

On ABS, PP, or PE, screen printing, pad printing, and UV printing are frequently used. Pre-treatments (e.g., corona/plasma) increase adhesion on low-energy surfaces. For textured surfaces, pad printing and contour-cut transfers are particularly suitable.

X-PCK backpack case

Depending on the surface structure, thermal transfer, high-quality patches, or UV printing on dimensionally stable areas are possible. This allows logos, phone numbers, pictograms, or QR codes to be integrated for clear legibility without compromising its function as a backpack case.

Foam inlays

Information labeling is often achieved through laser engraving in multi-layer foams (contrast reveal), printed top foams, or precisely fitted insert cards. This enables contours, tool and device locations, scales, and color coding to be displayed readably and reliably.

Panels, built-ins, and fronts

For the Mobile Work Table in a Case, front foils, control panels, and device interfaces are essential. UV printing, screen printing, or reverse-printed films enable durable scales, function labels, and standard-compliant symbols directly at the workstation.

Requirements for durability and legibility

In industrial use, printings must reliably withstand mechanical, chemical, and climatic stresses. Relevant criteria include:

• Abrasion resistance when in contact with gloves, tools, and stacking edges.
• Chemical resistance to cleaners, oils, lubricants, and disinfectants (e.g., in the medical technology environment).
• UV and weather resistance for outdoor applications.
• Temperature changes and condensation, especially for transport and equipment cases.

Protective laminates, cured inks, suitable pigments, and the right substrate build-up ensure the long-term legibility of logos, warning notices, scales, and codes.

Printing in the context of branding and corporate design

Printing is the interface between function and branding. Color accuracy (e.g., RAL or spot colors), consistent typography, and recurring design elements create recognition across the entire range — from demo and presentation cases to industrial and special cases to cases for medical technology, electrical engineering, and measuring instruments. For clear results, color references, vector data, and coordinated data handover are crucial.

Impact of printing on application areas

The functional role of printing differs by application:

• Demo cases and sample cases: CI-compliant logos, product names, serial and contact details; inside, clear allocation via labeled foam inlays.
• Presentation cases: high-quality surface graphics, image motifs, and precise typography; durable surfaces for frequent presentations.
• Equipment cases and transport cases: robust pictograms, ownership and location labeling, QR/DataMatrix codes for asset management.
• Industrial cases and special cases: standard-oriented markings, warning and safety symbols, unambiguous function labeling.
• Cases for medical technology, electrical engineering, measuring instruments: clear scales, inspection and calibration notes, serial numbers, traceable markings.
• Professional cases for tradespeople and machinery: robust, abrasion-resistant labeling, color coding for tool compartments, clearly visible, durable contact information.

Printing for the Mobile Work Table in a Case

For this special product, operability is paramount: function pictograms, connection labels, scales, and note fields are applied so they are clearly readable and within easy reach when open. Typical application fields are testing companies, IT service providers, service trades, mobile tradespeople, metrology manufacturers, HVAC, moderators, consultants, exhibition contractors, electrical plant engineering, electrical installation, and mechanical engineering. Printing here supports structured workflows, reduces operating errors, and makes temporary workplaces immediately usable.

Design and data requirements

To ensure printings are reproducible and precise, print data should be prepared cleanly from a technical standpoint:

• Vector graphics (e.g., with fonts converted to outlines) for logos and pictograms.
• Sufficient resolution for image motifs used in UV/digital printing.
• Specifications for spot colors, alternatively color profiles and binding color references.
• Defined minimum line weights and reversed areas (knockouts) for good legibility.
• Positioning and tolerance specifications, especially near fittings or rivets.

Quality assurance and testing

Typical tests address adhesion, abrasion, scratch resistance, solvent resistance, and color stability. Samples or print proofs for approval facilitate alignment. For variable data (serial numbers, codes), readability tests and spot functional checks are common.

Functional marking on foam inlays

Foam inlays can be equipped with position numbers, contour lines, symbols, and color coding. Laser engravings in multi-layer material create high-contrast, durable markings. Precision-fit foam inlays for cases enhance clarity, for example in demo and presentation cases with changing equipment.

Sustainability aspects

Material-appropriate, low-solvent, or UV-LED-cured systems reduce emissions. Durable printings extend product service life. Replaceable insert cards and modularly printed panels support repairability and updates without complete new production.

Legal and normative aspects (general)

When using logos, trademarks, and protected designs, rights and approvals must be observed. For safety symbols and warnings, valid standards and industry-standard pictograms should be used. Information on test or conformity markings should be maintained carefully and kept up to date. These notes are general in nature and do not constitute legal advice.

Typical placements and sight zones

Highly visible areas include outer lid surfaces, front and side surfaces, interior panels in the field of view, as well as top foams in the opened case. For transport containers, stacking and handle sides benefit from durable, abrasion-resistant prints. On the X-PCK backpack case, frontal viewing areas and smooth sections are suitable for clear, impact-resistant markings.

Integration of branding across series and variants

Series-capable printing supports variant management: consistent CI elements supplemented by variable modules such as serial numbers, QR codes, product lines, sites of use, or department identifiers. This ensures demo cases, equipment cases, and transport containers remain clearly attributable despite variety.

Coordination with the manufactory

As a specialized manufactory for B2B cases, KKC Koffer GmbH tailors printing solutions to material, application, and quantity. Close coordination between design, prepress, and production enables position-accurate results — for example around hole patterns, fittings, profiles, grip recesses, hinges, and latches, ensuring motifs do not intrude into functional areas.

Alternative and complementary identification methods

Depending on requirements, labels, vinyl cut graphics, domed elements, or embossed nameplates can complement printing. Laser engraving and front foils are particularly suitable where changing content or very high durability is required. For transport containers with heavy stress, a combination of printing and mechanically fastened nameplates can be expedient.

Practical recommendations for robust outcomes

1. Check the material and select the printing process to suit the material.
2. Create data in vector format, observe minimum line widths, define colors.
3. Keep sight zones and functional parts (handles, hinges) clear in motif planning.
4. Plan for sample approval, especially for spot colors and textured surfaces.
5. Consider protective measures (laminate, clear coat) for high-stress areas.
6. Secure variable data (serial numbers, codes) with verification routines.

Product context: printing across the diversity of cases

Whether cases, the X-PCK backpack case, the Mobile Work Table in a Case, aluminium cases, plastic cases, transport containers, or foam inlays: printing combines information, order, and branding into a functional whole. It increases reliability in processes — from presenting, measuring, and testing to daily service use.
