Colour and substrate checks in the PentaPlus QC lab

Standards

Certifications & Standards

What we are audited against, and what we hold ourselves to beyond it.

ISO 9001:2015
Quality Management System
PentaPlus is an ISO 9001:2015 certified printing and packaging solutions provider. The certification covers the whole chain — enquiry, prepress, press, finishing and dispatch — not just the shop floor.
Kappa Quality Standards
Six-sigma strategy
A six-sigma based strategy applied to print defects, so improvement is driven by measured variation rather than by complaint volume.
5S Work Culture
Workplace organisation model
Sort, set in order, shine, standardise, sustain — the model the plant floor is organised around, and the reason a make-ready is repeatable across shifts.
Closed-Loop Colour Management
GMG + X-Rite
Colour is measured continuously against the signed proof and corrected in the run, so the last sheet matches the first by number and not by eye.

Four gates

Where Quality Is Checked

Four gates, each with something measurable to pass.

01
Goods-in
GSM, moisture, COBB, bursting and tearing strength verified per lot before the substrate is scheduled.
02
Make-ready
Ink viscosity checked, ink keys set from the file, density brought onto the Star Proof target.
03
In-run
Closed-loop colour correction and X-Rite spectrophotometry hold density from first sheet to last.
04
Pre-dispatch
Laser-precision print inspection, then a 100% sort in the ISO sorting bay against the signed proof.

Instrumentation

The QC Lab

Nine instruments standing between a substrate and a scheduled job. Board is tested at goods-in, ink at make-ready, colour throughout the run.

Grammage per square metre
GSM Tester
Measures grammage per square meter, which is an important factor in the paper and packaging industry. Board that arrives under-weight is caught at goods-in, not at the folder-gluer.
Burst resistance of board
Bursting Strength Tester
Establishes how much pressure a board takes before it gives way — the number that decides whether a corrugated box survives a stacked pallet.
Tear propagation resistance
Tearing Strength Tester
Measures how readily a started tear runs. It is what separates a carton that opens where the perforation says from one that opens anywhere.
Water content in the substrate
Moisture Tester
Determines water content in materials. Board outside its moisture window curls on press and misregisters, so every lot is checked before it is scheduled.
Water absorption of paper
COBB Tester
Measures water absorption of paper — the predictor of how a substrate will take aqueous coating and how a pack will behave in a cold chain.
Bending resistance
Stiffness Tester
Assesses bending resistance. A carton needs enough stiffness to stand on a shelf and little enough to fold cleanly on the crease.
Breaking load under tension
Tensile Strength Tester
Assesses how much pull a material takes before failure — checked on every substrate that has to run through a high-speed converting line.
Ink flow characteristics
Viscosity Tester
Measures ink flow characteristics. Ink outside its viscosity band changes density mid-run, which is exactly the drift the closed-loop system is there to prevent.
Colour, by measurement
X-Rite Spectrophotometer
Provides precise, consistent and reliable sample measurement. Colour is signed off against a number, not against an opinion in a lightbox.
Crease and fold quality
Carton Board Creaser
Creases a sample under controlled pressure so the fold can be judged before a die is cut. A board that cracks along the crease has failed regardless of how well it printed.
