Why Line Thickness Matters

When preparing designs for textile printing, line thickness (also known as stroke width) is one of the most critical factors for achieving a high-quality result. Whether you use Direct to Film (DTF) or Direct to Garment (DTG), lines that are too thin can cause technical issues or lead to a less professional finish. Below, we explain what to consider to ensure a durable and sharp print.

Why Is the Correct Line Thickness Important? Using a minimum line thickness is not just an aesthetic choice — it is mainly a technical requirement:

Adhesion (DTF) With DTF transfers, an adhesive powder is applied to the ink. If a line is too thin, there is not enough surface area for the adhesive to properly bond to the film and, later, to the fabric. This can cause fine details to lift or peel during pressing or after multiple washes.

Visibility (DTG) With DTG printing, the ink is sprayed directly into the fibers of the garment. Very thin lines can get “absorbed” into the fabric texture, making them appear faint or even disappear against the background color of the garment.

Durability Designs with solid, thicker lines last longer. Thin lines are more vulnerable to wear and tear caused by friction and washing.

Question 2

VAT for Print on Demand

Accepted Answer

VAT for Print on Demand

We are a Dutch company, which means Dutch VAT rules apply to all orders placed with us.

Why do you pay VAT? VAT is charged on all our products. This is a statutory tax that we are required to pay to the Dutch tax authorities. VAT is therefore always included in the total price or listed separately on the invoice. For private customers, nothing changes: the price you see includes VAT.

VAT for business customers Are you a business customer based in the Netherlands? ➡️ You will always be charged VAT on your order. In many cases, this VAT can be included in your own VAT return, provided you are VAT-registered.

VAT reverse charge (Belgium and EU) There is an exception for Belgian businesses and other EU companies: Are you ordering as a business from Belgium (or another EU country)? And do you have a valid VAT number? In some cases, VAT can be reverse charged. This means we can invoice the order without Dutch VAT, and you account for the VAT in your own country. 👉 Important: This is only possible if we receive and can verify a valid VAT number before placing a new order. It will then be added to your account.

Important to know

We are required to charge Dutch VAT by default
VAT always applies unless a valid reverse-charge arrangement is in place
For EU businesses (such as Belgium), VAT can be reverse charged with a valid VAT number
If in doubt, always consult your accountant or financial advisor

Which Printing Technique Fits Your Designs?

Choose the Right Printing Method for Your Design A strong design is important — but choosing the right printing technique is just as essential. The technique determines both how your design looks and how it feels on the garment. In this guide, we explain clearly and concisely what to consider and which technique best suits your design.

Why Is Choosing the Right Printing Technique So Important? DTG and DTF are two different printing techniques, each with their own strengths. These advantages influence the look and feel of your design. Once you understand the differences, you can decide which technique best matches the image you want to create for your brand. By combining the right design, printing technique, and product, you maximize the impact of your design and create a professional end product that truly stands out.

DTG Printing (Direct to Garment) DTG is ideal for detailed and colorful designs. Advantages of DTG DTG is the perfect choice if you’re aiming for comfort, detail, and a premium look. The combination of a soft feel and sharp prints makes this technique ideal for high-quality and complex designs.

Custom order packaging

Accepted Answer

Custom Order Packaging

When you place an order with us, we always ensure that your products are packed neatly and securely. In most cases, we use standard plain shipping bags. These bags are durable and ideal for clothing items such as T-shirts or smaller products. If an order does not fit in a shipping bag, we switch to a cardboard box. This way, you can always be sure that your order arrives safely and undamaged at your customer’s address.

Option to Use Your Own Packaging Would you like to give your orders a more personal touch? You can supply your own packaging materials, such as branded or customized shipping bags or boxes. Once we receive your packaging, we will use it for packing and shipping your orders. It is important to take different sizes into account. For example:

A single T-shirt usually fits in a smaller letterbox package
Multiple hoodies require a larger shipping bag or box Make sure to supply packaging in multiple sizes, tailored to the products you offer.

Recommended Dimensions If you want to produce or order your own shipping bags, we recommend using at least the following dimensions to ensure compatibility with our fulfillment process:

Letterbox Package (e.g. 1 T-shirt) Minimum size: 240 × 350 + 50 mm This size ensures the package fits through the letterbox while still providing enough space to pack the product neatly.

Parcel (e.g. one or more hoodies) Minimum size: 360 × 500 + 50 mm This size is ideal f
