Custom t-shirt printing glossary

Every term you will run into when ordering custom printed shirts — explained in plain language, no industry jargon. From print technology and fabrics to art files and pricing.

Back Print

A back print is a large graphic on the back of a shirt — usually the company name, phone, and website — advertising readable from across the job site.

Cotton-Poly Blend

A cotton-poly blend (50/50 or 65/35) pairs the comfort of cotton with the durability of polyester — it shrinks less, wrinkles less, and dries faster.

Custom Jacket with Logo

A custom jacket with your logo is a rolling billboard on the road and the jobsite. A favorite of trucking companies — finished with a durable embroidered chest logo.

Design Proof (Mockup)

A design proof (mockup) is a visual of your printed shirt to approve before production — so you know exactly what you are getting before we print.

Dry-Fit (Performance Shirt)

A dry-fit shirt is a moisture-wicking polyester tee that pulls sweat away and dries fast — the top pick for crews working in the heat, from Florida to Texas.

DTF Printing (Direct to Film)

DTF printing is a digital heat-transfer method: full color, durability through dozens of washes, and pricing that makes sense from just 10 shirts.

Embroidered Hat with Your Logo

An embroidered hat puts your logo in stitched thread that does not fade, crack, or peel — a professional look that keeps advertising for years.

Embroidered Polo Shirt

An embroidered polo is the go-to for estimates and client meetings — machine embroidery looks premium and never wears off in the wash.

Embroidery (Machine Embroidery)

Embroidery is machine-stitched logo decoration in thread — an elegant, extremely durable way to brand polo shirts, hats, and company jackets.

Fabric Weight (oz and GSM)

Fabric weight is how much a material weighs per square yard (oz) or square meter (GSM) — it tells you how thick, durable, and breathable a shirt will be.

Free Shipping (40+ Pieces)

Free shipping kicks in at 40 pieces — delivery to all 50 US states at no extra cost. An easy way for businesses to cut the real cost per shirt.

Hi-Vis Safety Shirt

A hi-vis shirt is fluorescent safety apparel with reflective stripes — often required by ANSI safety rules on commercial jobsites across the US.

Hoodie (Hooded Sweatshirt)

A custom printed hoodie keeps your crew warm through the cold months — and a big full-color back print turns every jobsite into free advertising.

Left-Chest Print

A left-chest print is the classic small company logo placed at heart level — the most popular print placement on company shirts and workwear.

Logo Vectorization

Logo vectorization redraws a raster image (JPG, PNG) as a vector file you can scale to any size without losing sharpness.

Long-Sleeve Shirt

A long-sleeve shirt is a tee with long sleeves. Great for cooler months, and the DTF print is every bit as durable as on a short-sleeve shirt.

Minimum Order (MOQ)

Minimum order quantity (MOQ) is the smallest number of pieces you can order. At PodKoszulki.com it is just 10 shirts — with any size mix from S to 5XL.

Online T-Shirt Designer

An online t-shirt designer lets you create your print right in the browser. Ours is in development — for now, our team preps your design for free.

Price per Piece and Quantity Tiers

Price per piece drops as your order grows: a shirt with one front print starts at $13, and every quantity tier lowers the unit cost.

Print Care

Print care covers washing and drying printed shirts: wash inside out, use cold water, skip the bleach, and tumble dry low to keep graphics looking new.

Print Resolution (DPI)

DPI (dots per inch) measures print resolution. The higher the resolution of your logo file, the sharper and more detailed the finished print.

Ring-Spun Cotton (Combed)

Ring-spun cotton is yarn with smooth, aligned fibers — the shirt feels softer, lasts longer, and gives your logo a better printing surface.

Screen Printing

Screen printing is a traditional stencil-based method that only pays off on huge single-color runs. At PodKoszulki.com we use DTF instead.

Setup Fee

A setup fee is a one-time charge for print preparation, typical of screen printing. DTF has none — we prepare your print file for free.

Size Mix

A size mix lets you split one order across different shirt sizes — at PodKoszulki.com anything from S to 5XL at no extra cost.

Transparent PNG

A transparent PNG is an image file with an alpha channel — only your logo prints on the shirt, with no white box around the artwork.

Turnaround Time

Turnaround time is the window from proof approval to shipment of your finished shirts — standard is 5–7 business days, with a free quote in 24 hours.

Vector File (AI, EPS, SVG, PDF)

A vector file (AI, EPS, SVG, PDF) stores artwork as mathematical curves, so your logo scales to any size with zero loss of quality.
