Choosing blanks: how to compare garments properly

Compare blanks on five things: fabric weight in gsm, yarn type, fit and size consistency, dye consistency between batches, and supplier availability. Yarn type matters more than brand: ring-spun combed cotton prints noticeably cleaner than open-end. Pick two or three core styles at different price points and test them yourself rather than trusting a spec sheet.

Weight, yarn, fit and consistency matter more than the brand name. A framework for building a core range, plus regional supplier notes.

"Which blank is best" is the wrong question. The right one is: which two or three blanks cover most of my work, print reliably, and are actually in stock when I need them?

The five comparison criteria

Weight, in gsm. Around 150 is lightweight, 180 to 200 is mid-weight and the workhorse, 220 and up is heavyweight. Heavier fabric needs more ink and longer cure but hides an underbase better and feels more premium.

Yarn type. Ring-spun combed cotton has short fibres removed and is smoother; open-end is coarser and cheaper. On a fine halftone or a DTG print, the difference is visible. Two garments both labelled 100 percent cotton can behave nothing alike, and this is usually why.

Fit and size consistency. Modern versus classic cut, and how consistently a large is a large across a carton. Inconsistency here generates size complaints that look like your error.

Dye consistency. Do two cartons of the same colour match? This matters enormously on split deliveries and reorders, and it is the fault customers notice most.

Availability. A perfect garment that is out of stock in mid-size for three weeks is not a core garment. Reliability of supply belongs in the comparison, not as an afterthought.

Build a three-tier range

Tier Purpose Typical spec
Budget Price-driven bulk, events, giveaways 150 to 165 gsm, open-end
Core Most work, the default recommendation 180 to 200 gsm, ring-spun
Premium Retail-quality merch, DTG, fashion fits 200+ gsm, combed ring-spun, modern fit

Three tiers, one recommendation per enquiry. Customers who want cheaper have somewhere to go, customers who want better have somewhere to go, and you are not stocking twelve styles.

Test them yourself

Order a handful of each candidate and, on your own equipment, check:

  1. Print quality on the fine end of your typical artwork.
  2. Underbase opacity and how much white it takes.
  3. Cure behaviour, including any scorching on lighter fabrics.
  4. Shrinkage and print appearance after five washes.
  5. Size consistency across pieces.
  6. DTG results with your pretreat settings.

That is an afternoon and a small stock order, and it will save you a reprint argument within the year.

Regional supply

Availability is regional, and the shortest lead time usually beats the cheapest list price:

Pick one primary and one backup per tier. A single-supplier core range is a stockout waiting to become a missed date.

Watch the discontinuations

Fashion colours and seasonal lines get dropped, and finding out when a customer reorders is a bad way to find out. Prefer core catalogue lines for anything you expect to repeat, and keep the alternate style noted against the customer's design.

Costing, not just choosing

The blank is your largest single cost line, so a 30p difference across a few thousand garments a year is real money, and so is a stockout that loses a job. Both belong in your pricing formula, and holding decisions belong in your par levels.

Compare on landed cost, not list price

The price on the supplier's site is the least useful number in the comparison. What matters is what a saleable garment costs you by the time it is on your shelf and available in the size the customer wants.

Line Blank A Blank B
List price £2.10 £2.55
Freight share £0.18 £0.06
Case pack constraint 72, one colour 12, mixed
Realistic sell-through 70% 95%
Effective cost per sold unit £3.26 £2.75
Print quality Open-end, fair Ring-spun, good

The cheaper blank is 19 percent more expensive per garment you actually sell, before you account for it printing worse. This is the single most common sourcing error in decorating, and it is invisible until you do the arithmetic on sell-through rather than on purchase.

The test protocol worth running once

When you evaluate a candidate blank, put it through the worst job you do rather than the easiest. For most shops that is a white print on a dark garment, or a dense embroidery on a lightweight knit.

  1. Print your hardest job on it. White on black, full coverage, or an underbase plus four colours.
  2. Check dimensional stability. Measure body width and length, wash at 40, tumble dry, measure again.
  3. Wash-test the print. Five cycles minimum, stretch test the print surface after each.
  4. Check dye migration. Especially on poly blends and anything in a strong colour.
  5. Compare two batches. Order twice, a month apart, and compare colour and fit. Batch consistency is what decides whether reorders work.
  6. Record it all against the style so the next person does not repeat the test.

Step five is the one that gets skipped and the one that matters most for repeat club and school work, where this year's garment sits next to last year's on the same body.

Print time is part of the cost

A blank that needs an extra pretreat pass, a second underbase stroke or a slower press because the fabric is unstable costs you labour on every single garment. That cost is real and it is invisible on any spec sheet.

The measurable version: run the same design on two candidate blanks and clock both jobs. The job costing report will show labour per job and margin after labour side by side, and it is common for a blank costing 40p more to be the cheaper garment once press time is counted. That is the comparison to make before you commit a core line, not after.

Keep a live view of availability

A great blank you cannot get is a bad blank. Before you promise a date on a large job, availability matters more than price, and the answer needs to be current rather than remembered.

Where a supplier publishes a feed, sync it and check stock at quote time. Where they do not, import their catalogue and hold your own par levels on the lines you cannot afford to run out of, per inventory for blanks. Either way the goal is the same: nobody should discover a stock problem after the customer has approved a proof.

Printer's Friend holds supplier catalogues with live stock where a feed exists and CSV where it does not, so a quote can check availability before you promise a date, and the regional pages list the suppliers we sync per market.

Questions

What weight t-shirt is best for printing?
Around 180 to 200 gsm suits most work: heavy enough to feel substantial and to hide an underbase, light enough to be comfortable and affordable. Lighter fabric shows ink deposit and needs more care with cure.
Is ring-spun really worth the extra cost?
For anything with fine detail or DTG, yes. Ring-spun combed cotton has a smoother surface, so fewer stray fibres poke through the print and the result looks sharper. On plain single-colour work at a tight budget, open-end can be fine.
Should I offer customers a choice of blank?
Two or three, at clearly different price points, with a recommendation. More than that slows quoting down and creates stock complexity for no additional revenue.
How do I compare blanks on landed cost rather than list price?
Add freight, minimum order penalties and your own handling to the unit price, then divide by the units you can realistically sell. A cheaper blank that ships in case packs of 72 in one colour is not cheaper if you sell 20 and hold 52 for a year.
How many core styles should a shop hold?
Two or three per garment type at different price points, and no more. Every extra style multiplies your size and colour matrix, and the matrix is what fills a stockroom with dead stock. Breadth is a catalogue problem, not a shelf problem.
What should I do when a core line is discontinued?
Buy through the transition if the run rate justifies it, test the replacement immediately on your worst-case job, and tell affected repeat customers before they notice a difference. A quiet substitution on a club order is how a five-year account ends.
