Digital Printing Presses: What They Are and How They Differ from Flexo

A digital printing press is a production printer that images each job directly from a digital file, without plates or a fixed print cylinder. In label and packaging production, the common technologies are electrophotographic (toner) and inkjet; both are used for short to medium runs, versioned work, and fast job changeover. Digital is usually the better fit when runs are short, SKUs change often, or variable data is required; flexographic presses remain more economical for long, stable runs and for jobs where a plate-based process and conventional inks are preferred. The rest of this article explains the mechanism, the comparison points, and how to assess a press against your own production mix.

What a digital printing press does

A digital press receives a print-ready file, processes it through a digital front end (DFE) that handles color management, imposition, and job queuing, and then images the substrate directly. Because there is no plate to mount or register, the setup between jobs is largely a matter of loading the file and the substrate.

The practical consequences:

• Job changeover is short. A new job starts from a file, not a new plate set.
• Versioning and variable data are native. Each impression can differ, which suits serialized labels, regional variants, and short promotional runs.
• Make-ready consumes less substrate. There is no plate registration and ink-keying process to run through.
• Run economics favor shorter lengths. Because there is no plate cost to amortize, the cost per unit stays relatively flat as run length grows, while flexo cost per unit falls as plates and make-ready are spread over more impressions.

How digital differs from flexographic presses

Flexography is a plate-based relief process: ink is metered onto an anilox roll, transferred to a photopolymer plate on a cylinder, and pressed onto the substrate. Digital skips the plate and cylinder entirely. That single difference drives most of the operational contrasts.

Mark Andy, which supplies both flexographic and digital equipment, positions its offering as a full lifecycle solution built around the customer's business, covering consultancy, implementation, and support rather than equipment alone. That framing is useful when comparing vendors: the press is one part of a workflow that includes prepress, color management, finishing, and service access.

Where the boundary sits

The crossover point between digital and flexo is not fixed. It depends on plate cost, make-ready time, substrate price, and how often the job repeats. A shop running many short, distinct jobs will usually find digital cheaper per job even at moderate volumes; a shop running a few long, repeatable jobs will usually find flexo cheaper per impression. The honest answer is that the crossover must be calculated from your own job mix, not taken from a general rule.

What to evaluate before choosing a digital press

Substrate compatibility

Confirm the press handles the stocks you actually run, including the thickness range, liner types, and any specialty materials. Digital presses are more constrained here than flexo, and a press that cannot run your main substrate is disqualified regardless of print quality.

Print quality and color consistency

Ask for samples on your own substrate, not just vendor stock. Check fine text, small reverses, gradients, and how consistently color holds across a long run and from job to job. Color management through the DFE matters as much as the print engine.

Finishing integration

Decide whether you need inline finishing (die-cutting, varnish, slitting) or will finish near-line. Inline integration reduces handling but ties the finishing configuration to the press; near-line gives more flexibility but adds a step. Map this against your current finishing equipment before committing.

Workflow and prepress

A digital press shifts work into prepress: file preparation, color profiles, and job ticketing. Confirm the DFE fits your MIS and prepress workflow, and that your team can absorb the change. This is often the real implementation cost.

Service and support access

Downtime on a digital press is expensive because it is often a single point in the line. Check the vendor's local support model, response commitments, and parts and consumables availability. Mark Andy's materials emphasize local support access and a complete resource for pressroom consumables and service parts; verify what that means for your region and your specific press.

When digital is the better fit, and when flexo is

Digital tends to win when:

• Runs are short or the job mix is highly variable
• Versioning, personalization, or variable data is part of the work
• Fast turnaround and short changeover are competitive requirements
• Plate cost and make-ready waste are a meaningful share of job cost

Flexo tends to win when:

• Runs are long and repeatable
• The substrate or ink system is outside a digital press's supported range
• Cost per impression at volume is the deciding factor
• Existing plate and anilox infrastructure is already efficient

Many operations run both, using digital for short and variable work and flexo for long runs. That hybrid model is often more practical than replacing one process with the other.

Practical next steps

1. Characterize your job mix. Pull the last 6–12 months of jobs and sort by run length, substrate, number of versions, and repeat frequency. This is the input that determines the crossover point.
2. Build a cost model per job type. Include plates, make-ready time and waste, ink or toner, maintenance, and labor for changeover. Compare digital and flexo on the same jobs.
3. Request samples on your substrates. Test the specific stocks and the specific print content that matter to your customers.
4. Map the workflow change. Identify what moves into prepress and how the DFE connects to your MIS and finishing.
5. Verify support and consumables locally. Confirm service response, parts availability, and consumable supply for your region.
6. Request a consultation with the vendor. Mark Andy's site offers a consultation request path alongside equipment, services, and supplies information; use it to test the press against your characterized job mix rather than a generic demo.

The decision comes down to your own run-length distribution and substrate set. A press that fits those two constraints, with support you can reach, will outperform one chosen on print quality alone.
