Home/ PS Tutorials/ Online PS Tutorial: Business Card Design — 7 Mistakes to Avoid

You don't want to find the problem after the cards come back from the printer. This guide covers size, layout, and color, then CMYK correction and print-ready export, and lists the seven most common mistakes along the way. With the full Online PS workflow, designing your own card is entirely doable.

1. What a business card does, and the design basics

A business card is the most cost-effective introduction tool in modern networking and business, whether it represents a person or a company. It is standard to print, concise in wording, easy to carry, and easy to keep, and it works for anyone regardless of age, gender, or job title.

Because the card is the first “face” you show the outside world, the quality of its design feeds straight into the first impression you make. A well-designed card often earns an unexpected edge in partnership talks, hiring, and negotiations.

The three core design principles

  1. Keep the information brief and clear — only what is essential: name, title, company, contact details.
  2. Make the composition complete and legible — every element needs hierarchy, and the white space has to be right.
  3. Unify the visuals — color, type, and logo should all follow the corporate identity system (CIS).

2. Getting set up (opening Online PS)

2.1 Go to Online PS

Open your browser and visit Online PS (zaixianps.cc). That page is the browser-based Photoshop, with an almost complete feature set.

2.2 Create a new document

Step 1: File → New

Set the card size, resolution, and color mode:

  • Width: 9 cm (≈ 1062 px at 300 dpi)
  • Height: 5.5 cm (≈ 649 px at 300 dpi)
  • Resolution: 300 dpi (print grade)
  • Color mode: CMYK (switch to CMYK before export so the print color doesn't drift)
  • Background contents: White or Transparent (fill it yourself later)

If you only want a quick digital mock-up first, work in RGB and tick “Convert to CMYK” later under “File → Export → Export as PDF”.

2.3 Turn on rulers and guides

Step 2: Show rulers (Ctrl+R) and drag out four safety-margin guides

A standard card wants an inner margin of 3 mm (≈ 35 px) so nothing important gets trimmed off.

2.4 Save your working template

Once you have done File → Save As PSD/PEA (a Photoshop project file), you can pick the edit back up whenever you like and skip the setup work.

3. The full design workflow, from new document to layout

3.1 Background and base color

Step 3: New Shape → Rectangle

Press U (shape tool) → choose Rectangle → hold Shift and draw a rectangle the same size as the canvas.

Fill it with the company's primary color (CMYK) — C=0 M=0 Y=0 K=100 (pure black) or C=100 M=0 Y=0 K=0 (pure cyan), for example — and keep it to two colors at most.

3.2 Place the logo (or company mark)

Step 4: File → Open, then drag the logo in

Use a transparent PNG or .svg for the logo so it stays crisp on any background.

⚠️ Never use patterned color fills, photos of people, cartoons, or any other image unrelated to the corporate identity.

3.3 Add the text information

Step 5: Type tool (T)

Usual order of information (top left ↘ bottom right)

  • Name (12–14 pt)
  • Title / department (9–11 pt)
  • Company name (bold, 10–12 pt is best)
  • Phone / email / address (8–10 pt)

Stick to standard system faces (SimSun, Microsoft YaHei, Helvetica) or the company's own typeface, and avoid handwriting and cartoon fonts.

Use Paragraph Style → Alignment → Align Left/Center so the left and right margins stay inside the safe area.

3.4 Color correction and consistency

Step 6: Color panel → enter the CMYK values

Make sure every text color matches the brand palette. If you need more than two colors, stay within three (including the logo's spot color).

3.5 Check the details (error prevention)

Step 7: Zoom to 200% and check the type layout

Check that:

  • There are no spelling or punctuation errors.
  • Every text block sits inside the safe area.
  • Layers are named consistently (background / logo / text_name / text_contact) so later edits are easy.
  • There are no unnecessary layers, empty layers, or hidden fills.

4. The seven common mistakes (and how to avoid them)

  1. Too much information, unclear wording

    What it looks like: the card carries far too much unnecessary content — company history, a motto, a long self-introduction.

    How to avoid it: keep just six items in Photoshop: name, title, company, phone, email, address. Merge text layers with Ctrl+Shift+T so you don't carry layers you don't need.

  2. Wrong size, or an ill-advised folded design

    What it looks like: a square 10 cm × 10 cm card, or a folded or flip-open layout, chosen on a whim.

    How to avoid it: always use the standard 9 cm × 5.5 cm. Lock the aspect ratio when you create the document and don't stretch it yourself.

    If you genuinely need a custom size, confirm the trimmer's specs with the printer beforehand.

  3. Cluttered, undignified color

    What it looks like: overly bright colored backgrounds, patterns, or mixed colors — hot pink, purple, rainbow stripes.

    How to avoid it: use the CIS primary plus secondary color and keep the total to three or fewer (including the logo's spot color). Save the corporate palette as a swatch set in Photoshop and reuse it everywhere.

    ⚠️ Treat white, beige, pale blue, pale yellow, and light gray as safe background colors.

  4. Mixed scripts, traditional characters, or handwriting

    What it looks like: simplified and traditional Chinese and English fonts tangled on one card, sometimes with a handwritten signature or a scribble.

    How to avoid it: settle on one language (Simplified Chinese, or whatever the company standardizes on) and allow only one writing system per card. Set a single font family in the Type tool's options.

  5. Ignoring paper stock and print color correction

    What it looks like: highly saturated CMYK values on watercolor paper, which then print muddy or bleed.

    How to avoid it: switch to CMYK mode in Photoshop first, then preview with “View → Color Profile → Print CMYK”. If you need a spot color (PMS), tick “Output as spot color” when exporting the PDF and attach a color proof.

  6. Filling the card with mottoes or unrelated artwork

    What it looks like: a “life motto” squeezed into the blank space, plus decorative cartoons or pet photos.

    How to avoid it: keep the card focused on what's useful — only the identification that is actually needed. If you insist on decoration, make sure it doesn't compete with the information area and that its color is consistent (a light gray rule, for instance).

  7. More than three colors, no shared visual language

    What it looks like: four or five different colors on one card, so the whole thing reads as messy.

    How to avoid it: follow the “two main colors plus one accent” rule. Use Layer → New Fill Layer → Color Lookup to audition palettes quickly.

    Palette example:
    Primary (C=100 M=50 Y=0 K=0)
    Secondary (C=0 M=0 Y=0 K=80)
    Accent (C=0 M=30 Y=100 K=0)

5. Export and print recommendations

5.1 Export as PDF (recommended)

Step 8: File → Export As → PDF

  • Page size: tick “Use document size”.
  • Color conversion: CMYK (if the document is RGB, tick “Convert to CMYK”).
  • Compression: set images to “None” or “ZIP (maximum quality)” and make sure the print resolution is at least 300 dpi.
  • Before saving, enable “Include Bleed, 5 mm” — most printers ask for 3–5 mm of bleed.

5.2 Export as PNG/JPEG (screen use only)

For email or on-screen display, “Export As → PNG” (300 dpi) or “JPG” (maximum quality) is fine. Note that PNG is RGB: if you leave the conversion to the printer, the color may drift.

5.3 Check the pre-press file (PDF preflight)

  • Run Adobe Acrobat Preflight to confirm the file is CMYK and includes bleed.
  • Make sure all text is converted to outlines (tick “Convert fonts to outlines” in the PDF), so no font goes missing.
  • Compare against a color swatch book (Pantone / CMYK) and a physical proof, and ask the printer to color-correct if needed.

FAQ

Q1: How do I switch to CMYK in Photoshop?
Tick “Convert to CMYK” under “File → Export → Export as PDF”. For an immediate preview, open “View → Color Profile → CMYK” to see an approximation (the PDF output is still what counts).
Q2: Why does my text layer look blurry after exporting to PDF?
Most likely the text was rasterized. Make sure you have not applied filters or layer styles (drop shadow, outer glow) to the text layer before exporting, or choose “Keep Text” when you export the PDF.
Q3: How do I lay out 3 mm safety guides quickly?
  1. Turn on rulers (Ctrl+R).
  2. Drag four guides off the rulers (left, top, right, bottom), each 3 mm from the canvas edge (≈ 35 px at 300 dpi).
  3. Hold Shift to snap the guides perfectly horizontal or vertical, then check that every text block sits between the inner pair.
Q4: How do I add a QR code to the back of the card?
Use “File → Open” in Photoshop to load the generated QR code PNG (300 dpi is best), drag it onto the canvas, keep it between 12 mm and 15 mm, and place it so it doesn't crowd the important text.
