High-quality visuals are essential for creating professional documents, reports, and PDFs in Tuhund. Whether you are uploading a company logo, product images or other graphics, the quality of the image has a direct impact on how your documents look and feel. Tuhund’s printing engine is capable of producing exceptional quality outputs—but only if the source images are of good quality.
This guide explains the best practices for sending images to the Tuhund team, why format matters and how to avoid common pitfalls.
1. Sending Images via WhatsApp
If you are sharing images through WhatsApp, please take care of the following:
-
Avoid sending as a compressed image. By default, WhatsApp reduces image quality to save bandwidth.
-
Instead, send the file as a Document, not as a photo. This ensures the image is passed in its original resolution and without compression.
-
On mobile: when attaching, choose Document → Browse → Select Image File.
-
On desktop: use the Attach → Document option rather than Gallery.
This small step prevents automatic compression and preserves the original quality.
2. Understanding Generation Loss
When an image is saved, re-saved, or passed through multiple apps, each step may introduce generation loss—a gradual reduction in quality.
-
JPEG files are especially prone to this problem. Every time a JPEG is saved, it undergoes lossy compression, which degrades quality. Over time, edges become fuzzy and colours lose sharpness.
-
Common Mistake: Sometimes, when we request a PNG, customers take the old JPEG file they already have and simply re-save it as PNG. This does not improve quality. In fact, the original JPEG’s losses are preserved and sometimes additional quality loss is introduced. The result is usually worse than the original.
-
To truly benefit, the PNG should be exported directly from the original source file (vector file, design file, or camera image), not converted from a JPEG.
3. Recommended Formats for Best Quality
To maintain professional standards:
-
Use Vector Formats (Preferred): SVG, AI, EPS, or PDF. Vectors are resolution-independent and print perfectly at any size. Ideal for logos, brand marks and designs.
-
Use PNG (Next Best): For raster images (e.g., product photos), use high-resolution PNG directly from the original source, not a JPEG conversion.
-
High-Resolution TIFF: For professional printing, TIFF is also acceptable.
⚠️ Important Note about PDFs:
Saving a raster (pixel-based) image into Word and then exporting it as a PDF does not enhance its quality. If the original was low-resolution, the PDF will still contain the same low-resolution image. Only vector-based or true high-resolution images embedded directly will maintain quality inside a PDF.
4. Why Image Quality Matters in Tuhund
Tuhund’s reporting and printing system is designed to deliver sharp, precise, and professional-quality documents. A good image ensures your invoices, proposals, catalogues and certificates look elegant and trustworthy.
-
High-quality image: Crisp, vibrant and professional.
-
Low-resolution or repeatedly saved image: Blurry, pixelated and unprofessional—spoiling the overall appearance of an otherwise perfect document.
Remember: Tuhund can handle any design—but the results depend on what you feed into it.
5. Quick Checklist Before Sending Images
✔ Send files as documents on WhatsApp (not photos).
✔ Prefer vector formats (SVG, AI, EPS, PDF).
✔ If raster, use original high-resolution PNG (not JPEG converted to PNG).
✔ Avoid repeated saving/conversion of JPEGs.
✔ Don’t embed low-res images in Word and export as PDF expecting improvement.
✔ Double-check that logos are clear and backgrounds are transparent (if needed).
Final Note
With Tuhund, you get exceptional quality prints and PDFs. However, if low-quality or repeatedly compressed images are uploaded, even the best rendering system cannot fix poor resolution. By following these simple steps, you’ll ensure your company’s branding, logos and documents always look their absolute best—without the need for repeated reminders.
