Ink of the Week Winners

After some big wins at an engineering competition, students of the Ligonier Valley Middle and High School Engineering Teams were invited to be in the 2017 Fort Ligonier Days Parade. For the “Celebrating Our Past, Building Our Future” theme, students designed and built a float that showcased innovators from the past. They capped off the event by wearing custom shirts that said “Building Our Future” on the back. Awesome job, team!

The State College Area High School Drumline went loud and proud with their team shirts this year, featuring an Uncle Sam design and the phrase, “We want you…. To lose your hearing!” Their drumline is unique in that they don’t hold auditions to become members and welcome any and all interested students to participate. They have a great time together on Friday nights and couldn’t imagine drumming with any other group!

8 Specialty Printing Techniques to Make Your T-Shirts The Talk Of The Town

If you want your t-shirt designs to be unique, to stand out from the crowd, try using some of the specialty printing effects outlined in this article. Specialty printing offers some genuine advantages. Besides simply looking awesome, special effects give your designs a point of difference from others and while they do cost more than standard screen printing, distinctive products often command higher sale prices.

Discharge ink

Discharge ink removes the existing dye from a t-shirt, leaving behind the natural colour of the fibre (generally some shade of beige). Colours can then be replaced in the fibres by adding inks to the discharge base.

Advantages: Using discharge ink on a dark coloured t-shirt results in a solid, coloured print and a very soft hand (i.e. a soft ‘feel’ to the printed t-shirt). Discharge ink is especially valuable if you’re printing colours on black t-shirts. The alternative technique for printing colours on a dark dye base requires a “base” layer of white ink to ensure sufficient opacity of colour, resulting in a thick, heavy finish.
Disadvantages: Because it’s impossible to know in advance how each shirt will react to discharge ink, colour matching can’t be guaranteed and there may be some colour variation between prints throughout a run.

Photochromic ink

Photochromic, or UV-reactive inks, are almost transparent when viewed indoors but change to vivid colours in sunlight.

Advantages: Cool effects can be created with a print that effectively displays two different designs – one indoors, and another outdoors.
Disadvantages: Only a limited range of colours is available.

Glow in the dark ink

Glow in the dark inks do exactly what their name suggests – they distinguish themselves by glowing in the dark! In the light, these inks will appear semi-transparent.

Advantages: People can find you in the dark. (Just kidding. It’s pretty cool, though.)
Disadvantages: The inks work best if they’re printed on a white or pale coloured background, so a light coloured base layer is required on darker shirts.

Foil printing

Foil printing is a two-stage process which leaves a shiny metallic ‘print’ on the shirt. First, the garment is screenprinted, using a special adhesive rather than ink, and cured (dried) in the normal way. A sheet of foil is then heat-pressed onto the image created by the adhesive. When the press is lifted away, the foil sticks to the adhesive-printed areas and the excess is removed.

Advantages: Foil printing gives the best shiny metallic printing effect. Bling!
Disadvantages: Because it’s a two stage process, foil printing may not work quite as well for fine, detailed designs, and it’s more vulnerable to energetic washing than most other decoration styles.

Metallic inks

Metallic inks result in a shimmery, sparkly effect, rather like metallic car paint. Metallic screenprinting is cheaper than foil printing, but doesn’t have the same shiny effect.

Glitter printing

Like foil printing and metallic inks, glitter inks can make your design sparkly and eye-catching. They’re available in a variety of colours.

Puff inks

Puff inks are created by mixing a specially formulated base in with the ink. The base-ink mix expands (“puffs”) as the print is cured through the heat tunnel, leaving a 3D texture. Puff inks are also available in a wide range of colours.


Flock printing is achieved by adding a special base to the ink, which gives the ink a furry, velvety texture as it cures through the heat tunnel.

All of these specialty printing techniques can be used to give your designs a little “extra” something, make them special, unique.

What is the definition of GSM when purchasing fabric?

You’ve heard of a 50/50 or a 80/20 t-shirt. 50/50 means 50% cotton and 50% polyester or 80% cotton and 20% polyester (t shirt iron on transfer), but have you ever seen the gsm listed and wondered what that meant? Simply put; that’s the weight of the fabric.

But first, it’s important to know that GSM also has some other acronyms that do mean the same; let’s start with those.

GSM (also known as gm/2) = grams per square meter and is the metric measurement of the weight of a fabric.

Metric measurements are generally the most common place but some clothing items are still marked in Imperial weights (OZ or oz/yd2 = ounces per yard squared)

The important thing to state here is that all of the terms above are measurements of weight, specifically the fabric weight when talking clothing. For example a t-shirt may be listed as 185gsm and another may be listed as 5.5oz the outcome is that these are basically the same as 5.5oz = 186gsm

You can work out any conversion of OZ & GSM by using the following calculation

5.5oz x 33.906 = 186.48gsm
185gsm / 33.906 = 5.45oz

The math is an important part of understanding the variations of fabric weight but in day to day buying you won’t want to pull out a calculator in a shop to work out what is what!!

So the main question you may have is “What is a good weight to buy?”

That will depend on what your needs are. Fabric weight is in almost all cases is a definition of the thickness of the garment itself. If you want a heavy t-shirt then a 180-200gsm item is generally at the very top end of a t-shirt weight, but if you want a nice lightweight summer t-shirt a 130-150 is also great. Likewise if you are looking for a cheap promotional t-shirt that may not be worn more than a few times a 100-110gsm t-shirt can be more than adequate.

Hoodies & Sweatshirts work on the same basis a thick winter hoodie can be 300-400gsm but a nice all year round weight can be 250-300gsm and a summer weight hoodie can be 200-250gsm.

Will a heavier weight T shirt / hoodie / sweatshirt last longer or better quality?

The answer to that really depends on you and what you want from your garment. Will your customers wear it regularly (2-3 times a week)? If yes, then certainly I’d expect a heavier weight to last longer with all the extra washing and drying regular wear will mean. But I have many t-shirts that are 130-150gsm that have lasted for years with occasional wear.

As for the quality, that is such a wide range term that is always a matter of individual perspective. A designer t-shirt may cost $30 but only be 130gsm in weight and a “no brand” T shirt may cost $15 and be 190gsm.

But in general terms the higher the fabric weight most people would interpret to be better quality.

Does the higher the weight effect the price?

Yes; without a doubt. The higher the weight the more raw materials are used to weave the fabric in to its finished state ready for cutting and sewing.

What if there is no fabric weight in the listing I’m looking at?

To be honest there is no reason for the manufacturer or if looking it up in a catalog not to include the fabric weight of their clothing (especially if it’s a t-shirt, hoodie or sweatshirt) so in this situation it’s either the seller does not know or they do not want you to know?

If you’re looking at a t shirt, hoodie or sweatshirt and the GSM is not listed anywhere; ask the seller or manufacturer. If they don’t know or do not respond that would personally set off a red flag.

So in summary GSM is simply the fabric weight of a clothing item.

My chemical problem and the (maybe) solution

Emulsion, Plasticol, Screen cleaner dehazer, especially dehazer! Are bad news in my basement. I’ve got a seven yr old little girl, nosy neighbors, a deeply suspicious significant other, a well and a septic tank. I bought the Sgreen line of environmentally friendly gunk… and there is 75 feet of sand between the tank and the well, but if I give a detailed explanation about how all is safe people start questioning my credientials… and they’re not wrong. I don’t really know this stuff is safe, I just want it to be.

Most screenprinters (iron on transfers) don’t have to worry about this because a city waste water plant is fully capable of dealing with this breed of dirty water, so there’s little advice out there about it.

Here’s the plan I concocted to clean and reuse water so nothing ever goes into the ground (a one-sentence chemical argument-ending system!). Plz plz plz give me your advice as to how to improve it, cheaply:

Decorating Raglans with iron on stickers

Raglan tees have definitely caught on as one of the latest trends. Almost everywhere you look you can spot a raglan (baseball style tee) in a crowd of people. Using heat transfer vinyl to decorate these baseball tees is a great way to cash in on this latest fashion statement.

Tri-Blend Raglan Blank


Raglan shirts used to be thought of as just a baseball or softball practice option. While they are perfect for selling to teams, especially ones you already sell uniforms too, as practice jerseys, they are also great for fashion garments as well. If you are selling uniforms to a sports team, take advantage of the fact that you can offer raglans to the player’s family as well. For instance, shirts that say “baseball mom” or “baseball sister”. Why not throw in one for the grandparents, girlfriend, or aunts and uncles too? If you look around on Etsy or Pinterest, you will find tons of raglans decorated with many different quotes and designs such as Mom related sayings, monograms, and bachelorette designs.

With the raglan we created, we used a simple name and number design for the back of the shirt. For the front, we just used the small team emblem that was available in CadWorx Live. We cut this design using Siser Easyweed with our vinyl cutter.

Once we had cut and weeded our design, we heat applied at the recommended temperature of 305ºF for 10 seconds. A quick and simple design and the application was all this garment required. Think of the easy money to be made on a whole team’s practice shirts!

Tri-blends are an in demand garment choice right now, so make sure you offer this upgrade option to your buyers! If they get a chance to feel the difference between a 100% cotton raglan and a tri-blend, they are more than likely going to opt for the upgrade. That means more money in your pocket!
