Technical constraints

🔥 What not to do for a smooth process

  • On your external store, never duplicate a product created by TPOP: it would not be taken into account by our system if a customer placed an order with you.
  • Do not delete or modify the "SKUs".
  • Do not modify or delete the variants created (size / color), do not reverse the options (do not put the size in place of color and vice versa).
  • Do not change the type of product / "Distributor" - "Vendor".
  • Do not mark your orders as processed: we will do this automatically. If you process your orders, we will not be able to update your customer tracking number and you will not be able to cancel an order from our dashboard.
  • Do not delete an ordered product from your shop until it has been shipped: this may cause production problems.
  • Do not publish more than 1000 colors variants per day on your Shopify Store (this causes your products to be out of sync).


Fluorescent \ Neon colors

Whatever the medium, NEON colors should be avoided: fluorescent rendering is not printable.

If you send us a file with colors fluo integrated, we will print with the most similar rendering. The same applies to all specific colors (gold, silver, mirror effect...).


White (or similar) materials

On white materials (clothing or accessories) as well as on very light materials (beige, such as pockets or beige for natural color products) white is never printed.

For instance, white text on a white T-shirt will not be printed, nor will white text on a mug, pouch or tote bag.


Black on black

For rendering reasons, you should know that black color will never be printed on a black garment: the garment's color will replace the ink.


Image quality

The higher the resolution of your image, the more detailed your product will be.

As far as the dimensions of your visuals are concerned, make sure you send files that are at least 2000 pixels wide (and 5000 pixels maximum), in 150 DPI: the rendering will be top notch.

However, even if our printers allow us to render your visuals very precisely, textiles are less defined than a sheet of paper: micro-details may not appear properly, so take this into account before sending your visuals.


Destination country

If you place your orders manually from an external CMS, remember to select the country of destination (it is often forgotten): if this is not the case, you will be invoiced at the most expensive rate, that of a world delivery. We will not be able to rectify this billing once the order has gone into production, nor will we be able to give refunds (the operation is time-consuming and requires manual creation of the shipping label).

We therefore strongly advise you, for orders, to use the platform's creation module, which will save you the Shopify fees.

That's it. It's not much of a constraint, is it?
