Tips for crisp, professional prints
- Keep the proportions of the recommended size (for example 250 × 90 for the logo) so the image is not squashed or stretched.
- Use a PNG with a transparent or plain white background for signatures and seals — it blends cleanly into the document.
- Scan signatures in good light at high resolution, then crop tightly around the ink before uploading.
- Use a different signature per document if different people sign them — for example sales signs quotations, purchase signs purchase orders.
- After saving, open any quotation or invoice and preview it to confirm everything lines up.
Frequently asked questions
Where do I upload my company logo and signatures?
Click the Settings gear in the top-right corner and choose Organisation. Every upload option — logo, document signatures, header image and footer image — is on that one Companies Details screen.
Do I need a separate signature for each document?
Each document type has its own signature card: quotation, invoice, proforma invoice, purchase order and delivery challan. Upload the same image to all of them, or a different signatory for each.
What size should my logo and signature images be?
The logo is 250 × 90 pixels, each signature is 100 × 40, the header image is 275 × 110 and the footer image is 550 × 90. The size is also shown on each upload card.
What is the difference between the logo and the header image?
The logo is your brand mark. The header image is a full letterhead banner — it can include your logo, company name, address and contact details as a single picture.
Can I upload a company seal or stamp instead of a signature?
Yes. A signature card accepts any image, so you can upload a seal, a stamp, or a signature and seal combined into one picture.
How do I replace or remove an uploaded image?
To replace an image, choose a new file and click Upload. To remove it, click the red trash icon on the card. Click Save at the top to keep the change.
Is uploading a logo and signatures free?
Yes. Branding your documents with a logo, signatures and header and footer images is included in Catalystk's free plan.
