Fundamentals, definitions and simple scenarios. Good for freshers and warm-ups.
Illustrator creates vector graphics made of paths defined by mathematics, so a logo can be scaled from a business card to a billboard without losing quality, and colours can be changed easily.
Photoshop works with pixels, which become blurry when enlarged.
A logo should be delivered as a vector file (AI, EPS, SVG or PDF) plus raster exports.
Artboards are the printable or exportable areas in an Illustrator document, like pages.
One file can have many artboards of different sizes, for example a business card front and back, letterhead and social media sizes for one brand.
Each artboard can be exported separately.
Click to create anchor points with straight lines, click and drag to create curves with direction handles, hold Alt (Option) to break a handle and change direction, and hold Shift for 45-degree angles.
Good paths use as few anchor points as possible, placed at the extremes of curves, which gives smoother shapes that are easier to edit.
The Curvature tool is a simpler alternative.
The Selection tool (V) selects whole objects and the Direct Selection tool (A) selects individual anchor points and segments.
Others include shape tools, the Pen and Curvature tools, Type tool, Shape Builder, Eyedropper, Gradient tool, Width tool, Rotate, Reflect and Scale, Artboard tool and the Blend tool.
Learning their shortcuts makes work much faster.
Fill is the colour, gradient or pattern inside a shape, and stroke is the outline along its path, with settings for weight, caps, corners, alignment (inside, centre or outside) and dashes. Strokes can be given variable width with the Width tool and converted to filled shapes with Outline Stroke, which is useful for logos and scaling.
Grouping (Ctrl/Cmd+G) keeps related objects together, and isolation mode lets you edit inside a group.
Layers organise complex artwork into parts that can be locked or hidden.
Arrange commands (bring to front, send backward and so on) change stacking order within a layer.
Naming layers and groups helps when files are shared.
The Align panel lines objects up by their left, centre, right, top, middle or bottom edges, relative to the selection, a key object or the artboard.
Distribute spaces objects evenly, either by their edges and centres or with a specific gap.
Smart guides and the grid also help with precise placement.
Creating outlines (Ctrl/Cmd+Shift+O) turns text into vector shapes, so the file displays correctly on computers without the font, which matters for logos and print files, and the letters can be edited as shapes. The text is no longer editable, so I keep an editable copy of the file before outlining.
AI is the editable native format, EPS is an older vector exchange format still requested by some printers, SVG is for web graphics and icons, PDF is for print and sharing (and can keep Illustrator editing), and PNG or JPG are raster exports for web and presentations. Logos are usually delivered in all of these.
A clipping mask uses a top object's shape to show only the parts of the objects beneath it that fall inside it, such as placing a photo or pattern inside text or a circle. It is created with Object > Clipping Mask > Make (Ctrl/Cmd+7) and is non-destructive, so the contents can be moved or edited and the mask released later.
Image Trace converts raster images, such as a sketch or a low-resolution logo, into vector paths using presets such as Black and White Logo, Sketched Art or several colour options, with controls for paths, corners and noise.
After expanding the result, the paths need cleaning.
For professional logos, manual redrawing with the Pen tool usually gives cleaner results.
Applied problems, trade-offs and questions about your own projects.
Pathfinder combines and cuts shapes: Unite merges shapes, Minus Front subtracts the top shape, Intersect keeps only the overlap, Exclude removes the overlap, and Divide splits shapes into all their pieces.
The Shape Builder tool does similar work interactively by dragging across regions.
These are key for building logos and icons from simple shapes.
The Appearance panel shows and edits all fills, strokes and effects of an object.
You can add multiple fills and strokes to one object, for example a thick outer stroke and a thinner inner stroke, and apply effects such as drop shadows or offset paths that stay editable.
Saved as graphic styles, appearances can be reused across objects.
Swatches store colours for reuse.
A global swatch updates every object that uses it when you edit it, which is ideal for brand colours.
Spot colour swatches, such as Pantone, are printed with special premixed inks.
Organising swatches into colour groups and libraries keeps brand work consistent.
Symbols are reusable art saved in the Symbols panel.
Every instance links back to the master, so editing the symbol updates all instances, which saves time and file size for repeated elements like icons, map markers or patterns.
Dynamic symbols let instances have different colours while keeping the same shape.
Recolor Artwork changes all the colours in selected artwork at once using a colour wheel, colour groups or by mapping existing colours to new ones.
It is used to create colour variations of logos and illustrations, apply brand palettes, reduce artwork to a limited number of colours for screen printing, and generate harmonies.
Generative Recolor can suggest palettes from prompts.
Linear, radial and freeform gradients blend colours across a shape, with stops, angles and opacity that can be edited directly on the artwork.
Freeform gradients place colour points freely for natural shading.
A gradient mesh turns an object into a grid of points, each with its own colour, allowing photorealistic shading, though it is complex to edit.
Calligraphic brushes imitate pen nibs, scatter brushes scatter copies of an object along a path, art brushes stretch artwork along a path, bristle brushes simulate paint strokes, and pattern brushes repeat tiles along a path with corner tiles, such as for borders and chains. Brushes can be created from your own artwork and applied to any path.
Select the artwork and choose Object > Pattern > Make to enter pattern editing mode, where you see the repeat live, choose a tile type (grid, brick or hex), adjust tile size and spacing, and fix edges so it repeats seamlessly. The pattern is saved as a swatch that can be applied as a fill, scaled and rotated independently of the shape.
Offset Path creates a new path a set distance inside or outside the original, used for outlines around text and logos, stickers with borders, and cutting lines.
Outline Stroke converts a stroke into a filled shape so it scales correctly and can be combined with other shapes in Pathfinder.
Both are common steps in preparing logos and print files.
Point type is a single line that grows as you type, suited to headlines and labels.
Area type flows text inside a shape with automatic line breaks, suited to paragraphs and threaded text across several frames.
Type on a path places text along any path, such as a circle for badges and logos, with options to flip it and adjust spacing.
Envelope distort reshapes artwork using a warp preset, a mesh grid or a top object, such as bending text into an arch or fitting a design onto a flag shape.
Warp effects under Effect > Warp do similar distortions but stay live and editable in the Appearance panel.
Expanding them turns the result into regular paths.
System design, deep internals, leadership and tough follow-ups.
I set the document to CMYK with the final size and add bleed, usually 3 mm.
I use global or spot colours as required, convert fonts to outlines or package the fonts, embed or package linked images at 300 PPI, check overprint settings and rich black, and run the Separations Preview.
Then I export a PDF/X file with crop marks and bleed as the printer requests.
I study the brief, brand values, audience and competitors, then sketch many ideas on paper before going digital.
I build the strongest concepts in Illustrator with clean geometry, test them in black and white and at small sizes, and present two or three with reasoning and mock-ups.
After refinement I deliver a logo pack: primary, secondary and icon versions, colour, mono and reversed, in AI, EPS, SVG, PDF and PNG, with a simple usage guide.
I choose typefaces that suit the brand and work at every size, set clear hierarchy, and adjust kerning and tracking manually for headlines and logos.
I use paragraph and character styles for consistency, check that fonts are licensed for commercial use, and outline text in final logo files.
For packaging I follow legal minimum type sizes and check legibility on the actual material.
Work on a grid that matches the output size, such as 24 by 24 pixels, with keylines for consistent proportions, enable Align to Pixel Grid, use whole-number coordinates and consistent stroke widths, corner radii and visual weight across the set, check icons at 100% zoom and in pixel preview, and export clean SVGs with outlined strokes or consistent stroke settings.
Use Export As or Asset Export with SVG settings: presentation attributes or internal CSS, minimal decimal places, fonts converted to outlines, and Responsive enabled.
Clean the artwork first by removing hidden objects, unnecessary groups and clipping masks, combine paths and name layers for meaningful IDs.
Tools such as SVGO reduce file size further, and SVGs should include accessible titles where needed.
Start from the printer's dieline on its own layer, set as a spot colour and not printed. Add bleed beyond cut lines and keep text inside safe areas, use CMYK and spot colours as specified, set up special finishes such as varnish, foil or white ink on separate spot colour layers set to overprint, check barcodes, legal text and minimum font sizes, and supply a PDF/X with separations checked.
Firefly-powered tools in Illustrator can generate editable vector graphics, patterns and recoloured variations from prompts, which helps with early ideas and backgrounds.
I use them for exploration, then refine and redraw the final work so it is original, consistent with the brand and clean.
Clients' policies on AI use and disclosure, and trademark checks for logos, must be respected.
Define rules first: grid, stroke weights, corner styles, colour palette, perspective, level of detail and line style, documented in a style guide. Build reusable components as symbols and global colours, name and organise files consistently, export through Asset Export with naming conventions, and share libraries so other designers can produce new illustrations that match the system.
