Production Tolerances Explained
Thank you for your order, it means a lot to our small business.
We often get asked why production tolerances exist in printed packaging,
so we’ve created this guide to help you understand the reasons behind them.
- Quantity Tolerance
Every manufacturer and production method has a quantity tolerance, typically +/-10%. For very small Orders, this can be as much as +/-25%, while large-scale orders may have a tighter tolerance of +/-5%.
Why does this happen?
Packaging production involves multiple stages:
- Material preparation (paper, film, fabric)
- Printing setup (initial sheets may have quality issues)
- Conversion (cutting, gluing, stitching, etc.)
- Final quality checks
Due to these steps, the final quantity can vary. If the delivered quantity is within the stated tolerance, the order is considered complete. You’ll only be charged for what is supplied. If there’s an overrun, the extras are chargeable, they’re not free, as the factory incurs costs for them.
We always state quantity tolerances clearly on your order form. By placing an order, you agree to these terms.
Sometimes the final number exceeds the 10% tolerance but we cap it at 10% overrun and anything over and above this tolerance is supplied free of charge or we keep it in our warehouse as a backup stock if needed in the future.
- Size and Grade Tolerances
- Tooled packaging (e.g., glued boxes): Size tolerance is typically +/- 1mm or 2mm due to glue application.
- Non-glued tooled products: Should match the exact size ordered.
- Flexo packaging (e.g., flexible bags, sheets): Industry standard is +/-5% though we aim for +/-3%. This method involves folding, creasing, and gluing, which introduces more variability.
If your product must be an exact size, please discuss this with us before placing your order. We would hate for the packaging not to fit!
- Ink Colour Variance
Using Pantone colours allows for more controlled results. However, due
to recent changes between Adobe and Pantone, many clients now submit
artwork in CMYK or RGB. If conversion to Pantone is needed, we can assist
but final colour responsibility and decision lies with you.
How we manage colour:
- Ink is mixed using software linked to the printer.
- Colour is checked every 50–100 units during production.
- Colour consistency is maintained within a 5% Delta E tolerance (we aim for 3%).
Note: On porous substrates like brown kraft paper, ink absorption can affect colour appearance.
- Substrate Tolerance
We aim to show you a physical sample of the raw material before production. However, paper and board materials vary by batch — similar to wallpaper or wool. The same applies for fabric materials.
This can affect:
- Shade of material
- Texture and finish
- Ink absorption due to porosity of the paper
- Final ink colour outcome
We try to match previous samples when possible, but exact replication isn’t guaranteed.
Final Notes
- If you cannot accept a quantity tolerance, let us know. We can quote including the full 10% allowed overs, which will increase your unit price but ensure your invoice matches your order form. You might end up paying more than you should choosing this option.
- If you do not agree to these industry-standard tolerances, please inform us before placing your order. We’ll void the original paperwork and re-quote accordingly but sometimes we may not be able to support your request if it falls out with manageable criteria.
