Some product variants need alternative design files, for example:
White on white
DTG printing doesn't allow white on white prints. Your black variants might have a white print, but your white variants will need an alternative design file.
Increasing contrast
Some design files will look great one one colour but won't contrast well with another, but alternative colours in your design file could make all the difference.
In both cases one design file will work for some, if not most variants, but you'll want to overwrite this with an alternative for some variants. In either case it's best to upload a master file, and then upload any alternative design files to the variants that require them.
Adding alternative design files
Head to your WooCommerce product linking page at Account > Integrations > WooCommerce > Link products.
Scroll to the bottom of the linking page. You'll find headings for Mockups and Designs.
Under the Designs heading you should have a file already saved. To make things a little easier for yourself, you want this file to be what's being applied to the majority of your variants. If it already is, leave as-is and move to the next step.
If you need to upload a new master file, delete what's there then click Upload. Browse for your design file to upload it, then select which decoration area this design applies to.
If you select an embroidery position you will see the option to select your thread colours appear. You can select up to six.
If you don't select any thread colours here we can't guarantee which threads will be used during production. Any mismatch will not be deemed a fault.
Fixing the red exclamation error
If you see a red exclamation mark appear when uploading your design file it means your file has not been saved with the correct dimensions for decoration.
If this isn't corrected, the system will fill the decoration boundary with your file resulting in warped prints. You can see the design warp in the preview box, indicating how it will print.
To fix this, take note of the dimensions below the decoration position and re-save your design file to these dimensions. Alternatively, you can use the Photoshop templates available on each product page to position your designs and save to the correct dimensions.
With your master design file saved you can upload custom design files to any variants that require them.
Uploading custom variant design files
Scroll to any variant requiring an alternative design file.
In the right hand column you'll find the options for uploading alternative design files. Following the same process as above, click the Upload button and browse for your alternative design file.
If you're using the same embroidery design with different thread colours, take care to select the correct thread colours for each variant.
You will need to do this for each variant needing its own design file. If you see the red exclamation error during this process, correct your design file dimensions and re-upload before saving.
Adding mockups
Scroll back to the bottom of the page to find the Mockups heading. Mockups are used during production to assess the decoration result.
The system will automatically display any images available from your WooCommerce product page here. Click any you would like to use for mockups to add them to the product link. Alternatively, you can upload additional files using the Upload button.
For each mockup uploaded, select which decoration area it relates to. We don't necessarily need one for each colour variant but you have the option to add them if relevant.
Your mockups must be representative of a decoration that Inkthreadable can achieve. Uploading unachievable mockups resulting in products that don't match will not be considered a production fault. You can download mockups from any Inkthreadable product page to upload here if needed.
Make sure to click the Save button before returning to your product linking page to work ono other products.
